Mancow Muller

In January 2019, Muller returned to radio on WLS to host mornings.

On January 3, 2019 Muller returned to WLS in Chicago after nine months off the air. Muller said his new show will focus more on news, entertainment and politics compared to his time on The Loop.

Muller returned to the radio on Chicago's WLUP-FM radio station in February 2015 after winning a week-long audition for the station's 6 – 10  am weekday show. Muller's show on WLUP ended on 6 March 2018 when it was announced that WLUP had been sold to Christian radio broadcaster Educational Media Foundation.

Questions were later raised about the validity of the procedure. South had no formal training in waterboarding and had never before performed the procedure, leading the online celebrity and gossip site Gawker to accuse Muller of faking the whole thing. Muller later stated in an interview on Countdown with Keith Olbermann, "I admit it, it was a stupid radio stunt. But waterboarding, all it is, is water in your nose and mouth with your head back." Further adding "We went into this thinking it was going to be a joke. But it was not a joke – it was horrible. 'Hoax' is probably not the right word, but we did think it was going to be a joke."

On October 22, 2012, Muller began his new show, simply titled Mancow, on WPWR-TV, a live broadcast of his current radio show The Mancow Experience, with co-host Teresa Cesario. In February 2013, a program called The Mancow Mashup began airing on the network, which was a half-hour program that showed highlights from the previous morning's Television show. The show's last airing was October 7, 2014. On October 9, 2014, roughly a year from when the show began airing, Muller's WPWR-TV simulcast of his radio show was confirmed cancelled after the show's contract expired, along with The Mancow Mashup. Muller confirmed that for the first time since 1985, he will be taking a break from both TV and radio. However, Muller mentioned the possibility of other ventures, including a potential movie review show.

On May 22, 2009, Muller had himself waterboarded during his radio program on WLS, having lost a listener poll determining whether he or co-host Pat Cassidy would be the one waterboarded. The talk show host had previously claimed that calling waterboarding "torture" was wrong, something he had stated that he hoped his reenactment would prove. Lasting only 6 seconds ("8 seconds less than the average person", according to program guest Marine Sergeant Klay South), Mancow afterward changed his opinion, saying, "It is way worse than I thought it would be, and that's no joke", and described waterboarding as "absolutely torture".

On October 22, 2008, WLS in Chicago announced that Muller, along with Pat Cassidy, would join that station as a weekday radio talk show host, in the 9 am to 11 am time slot, beginning on October 27, 2008. Muller continued to host his nationally syndicated morning radio program. Just four months after the debut of Mancow and Cassidy, Arbitron ratings had the show at No. 1 in the 12+ audience, and nearly doubling Chicago competitors in the male demographic as of February 2009. Despite the ratings, Muller was fired from his job on news and conservative talk station WLS after only 16 months. Muller then hosted a Sunday night show on WABC-AM from September 2010 until October 2011, when he was let go following Cumulus Media's acquisition of WABC parent Citadel Broadcasting.

Muller's Mancow's Morning Madhouse ended its live run on Emmis' Alternative outlet in Spring 2006, and had the highest rated audience in Chicago with men ages 25 to 54 (among English speaking stations). According to the Arbitron radio ratings service, Mancow's show, measured in Average Quarter Hour listening percentages (AQH) had a 5.7 share. The next closest station was all-news WBBM with a 5.3 share.

On November 20, 2005, Ray Hofstatter, aka, "Cowboy Ray", a forty-five-year-old mentally challenged frequent caller and guest on Mancow's Morning Madhouse was struck by a car in a hit-and-run accident and critically injured. Ray died shortly after his life support was terminated on January 11, 2006. Muller offered a $13,000 reward for information leading to the arrest of the driver, but was unsuccessful. The hit-and-run case of Cowboy Ray was featured on Fox's America's Most Wanted television show on February 25, 2006. As of March 2019, the driver responsible had still not been found.

Mancow was an outspoken supporter of George W. Bush during the 2000 presidential election, asking people on the street whether they "liked [George W.] Bush or liked D-ck [Cheney]." On December 6, 2005, Muller made an appearance on Fox News Channel's Fox & Friends where he referred to Democratic National Committee chairman Howard Dean as "vile", "bloodthirsty" and "evil". Muller also commented on Dean's negative opinions on the War in Iraq, calling Dean a traitor who "ought to be kicked out of America" and "tried for treason".

For a full week leading up to Limp Bizkit's Summer Sanitarium 2003 concert in Chicago, Muller continually mocked the band's vocalist Fred Durst on his radio show and invited listeners to attend the concert with anti-Durst placards. When Muller's fans complied by showing up with the placards, openly taunting the singer, booing him and pelting him with refuse, Durst erupted into a profanity-laced homophobic tirade and left the stage only 17 minutes into the show. Durst was eventually sued for breach of contract (for not completing the show) by Chicago lawyer Michael Young in a class-action suit.

Muller married Sandy Ferrando, a former publicist on February 14, 2003. He has twin daughters named Ava Grace and Isabella Sofia. His father, a former traveling salesman, died of cancer at the age of sixty-two. The event deeply affected Muller and in part prompted him to write his first book, Dad, Dames, Demons and a Dwarf. Mancow Muller attended Harvest Bible Chapel from 2014 to 2019 and was a personal friend of pastor James Macdonald since 2016. In November 2018 Muller travelled to Israel with MacDonald where he baptized him in the Jordan River. Less than two months later in January 2019 and less than three weeks after starting his new radio show on WLS-Chicago, Mancow began calling MacDonald a con artist on his show and on social media sites, and asking him to resign or be removed as pastor. Mancow has consistently criticized and accused MacDonald of crimes since January 2019, including murder-for-hire in May, 2019.

Within two Arbitron ratings periods Muller took the station's 19th-ranked morning show to 5th-ranked among all teens and adults, and first among 18- to 34-year-olds. During his run on Q101, Mancow had a much publicized feud with fellow "shock-jock" Howard Stern. He also had close on and off air relationships with "Crazy Howard" McGee of WGCI-FM and Mike North of WSCR. McGee and Mancow's shows ran at the same time but catered to different demographics (WGCI is an R&B and hip hop station). In 2000, Mancow pulled an April Fool's day prank on his McGee by switching his transmitter with that of WGCI, causing McGee to unknowingly broadcast on Q101's frequency while Mancow introduced himself as the "White Czar" and taunted McGee on his own station. This caused a barrage of calls from listeners in McGee's defense. McGee was confused as he took many of the calls, but did not realize for over an hour that he was the butt of a joke. After realizing the prank, McGee played along for the remainder of the segment.

His show, however, was not without controversy. In 1999, Janet Dahl, the wife of Chicago talk radio host Steve Dahl, filed a multimillion-dollar lawsuit against Muller over lewd comments Muller made about her on his show. In 2001, the case was settled out of court. Although the terms of the deal were not disclosed, it reportedly reached seven figures.

Between 1999 and 2004, David Edward Smith's Citizens for Community Values filed 66 indecency complaints with the FCC relating to Muller's program, leading to 6 citations and $42,000 in fines. In 2004 Muller sued Smith for harassment and business interference, but later dropped the lawsuit. Emmis Communications entered into a 2004 consent decree with the FCC, agreeing to make a $300,000 "voluntary payment" to resolve the complaints; in 2006 (after Muller had ended his WKQX show), the FCC rejected Smith's challenge to this settlement.

Originally, Muller broadcast from WRCX-FM (Rock 103.5) studios in the John Hancock Center and in 1998, moved to the city's alternative rock station, WKQX-FM (Q-101) 101.1, where the show was broadcast from the Merchandise Mart for eight more years.

Muller accepted a job offer by Evergreen Media President Jim de Castro at more than double his salary to move to Chicago and work at "Rock 103.5" (WRCX). Muller's radio show, Mancow's Morning Madhouse, debuted in July 1994.

After his early hometown success, Muller left Kansas City for a brief stint at KDON-FM in Salinas, California. Then he headed north to San Francisco and KYLD-FM, "Wild 107". Now going by his old college nickname Mancow, in 1993 Muller made national headlines with a publicity stunt that caused a major traffic problem for San Francisco. Reacting to a subsequently debunked story that President Bill Clinton had tied up air traffic at Los Angeles International Airport for over an hour while getting a haircut from celebrity hairstylist Cristophe aboard Air Force One, Muller staged a parody of the incident on the San Francisco–Oakland Bay Bridge during rush hour. He used vans to block the westbound lanes on the bridge while his then-sidekick, Jesus "Chuy" Gomez, received a haircut. As a result of the publicity stunt, Muller was charged with creating a public nuisance. After entering a no contest plea, his sentence included three years probation, a $500 fine and 100 hours of community service. The radio station settled a civil suit by paying $1.5 million, including $500,000 to cover three toll-free days on the bridge.

Following high school, Muller attended college at Central Missouri State University (now University of Central Missouri) in Warrensburg, not far from the Kansas City metropolitan area. At CMSU he continued to work in theater, and it was his role as a half-man, half-beast in one production that gave rise to his nickname "Mancow". Muller earned double degrees from the university in Public Relations and Theatre in 1990. To earn money while in school, he operated his own mobile DJ business, providing music for school dances, weddings, and class reunions, a job he later said he hated. It was also while in college he took his first tentative steps into broadcasting.

Muller's radio career began while he was in college. He got a job at KOKO in Warrensburg as a late night control board operator, playing local commercials during satellite broadcasts of The Larry King Show. His role at the station gradually expanded until he got his own afternoon show. Among Muller's fans was the general manager of KLSI-FM, Kansas City, who offered him a full-time job as head of station promotions. Muller accepted the position, plus a weekend air shift, while completing his final semester at Central Missouri State. After graduating in 1990, Muller was hired as the morning drive air talent at Kansas City's KBEQ-FM, Q-104, where the Holy Moley & Maxx Show quickly rose to #1 in the ratings and helped Q-104 dominate the market.
