Nathan Barnatt

In 2019, Barnatt created a YouTube channel called Dad, an ARG which follows the story of a middle aged man known as Dad.

In August 2019, Barnatt appeared as a guest on an episode of Rental Reviews in which they reviewed the 1971 film Duel, and appeared again in September 2019, this time reviewing the 1982 film First Blood both as himself and Keith Apicary.

In July 2018, Barnatt played a fast-talking salesman trying to sell a faceless customer a copy of a fictional game called Finger GunZ, however the customer is repeatedly drawn to the gameplay of Sonic Mania Plus. Deliberately edited to look and sound like a 1990s commercial, the customer talks about all the features of Sonic Mania Plus and its low price while Barnatt repeatedly tries to sell Finger GunZ with comments taking direct jabs at the games industry.

In June 2016, Barnatt appeared as a guest on the Let's Play webseries Game Grumps. And in November 2016, Barnatt appeared in an episode of James & Mike Mondays, alongside his good friend James Rolfe, whom he worked with on Rolfe's 2014 film Angry Video Game Nerd: The Movie. On December 20, 2016, he again appeared as his character Keith Apicary in a Christmas episode of the Angry Video Game Nerd episode where he dresses up as Will Ferrell's Elf in order to secure Santa's gifts, and he and the Nerd play a variety of games with different Sega Genesis accessories while destroying the set in a slapstick fashion. He also appears in a short film by James Rolfe (a.k.a. Angry Video Game Nerd) called "Flying Fuckernauts vs. the Astro Bastards" as one of two Fuckernauts alongside Rolfe playing the other one.

In 2015, Barnatt played a police officer in the music video for "Sugar" by Robin Schulz. He was also featured as a dancer in the music video for "Pop Culture" by Madeon.

In 2012, Barnatt was featured on the front cover of LA Weekly magazine, covering his success on YouTube. In 2013, Barnatt provided voice work on the Animation Domination show High School USA! as one of the main characters, Lamort Blackstein.

Barnatt appeared on Comedy Central's The Gong Show with Dave Attell in 2008, on Comedy Central's Ghosts/Aliens pilot in 2009, and on This Show Will Get You High in 2010. In 2012, Barnatt developed a show with Adult Swim based on his Keith Apicary character called Youth Large. The Youth Large pilot was written by Barnatt, his brother Seth, and Paul Cummings (who is also the director). However, Adult Swim passed on the pilot but it was released online in August 2014. Since then Barnatt has sold shows to television networks Nickelodeon, Amazon, Comedy Central, Fox and Viceland.
