SMBC Theater

Weinersmith launched a side project linked with SMBC called SMBC Theater featuring skits and short videos put up on YouTube. This was normally updated once a week on Mondays with one or two short sketches and as of February 24, 2018 the channel had about 80,000 subscribers. Certain holiday clips are marked "part one", although very few have a second part. Despite its one-shot style there were certain characters who have received multiple storylines, such as James Ashby as president, J.P. Nickel's news stories, Jon Brence's dating shorts, and Weinersmith as Jesus/James Ashby as God. All the videos are satirical.

In August 2011, a project was successfully crowdfunded on Kickstarter called "SMBC Theater Goes TO SPACE!". This became Starpocalypse, a space opera webseries, which was released on 25 December 2013. It was released on their YouTube channel on May 3, 2015.

The channel stopped producing content between 2015 and 2020 when James Ashby started making Hand to Mouth skits.
