At the 2012 San Diego Comic-Con International, Stan Lee announced his new YouTube channel, "Stan Lee's World of Heroes", which airs several programs created by Lee and other creators. One of them, "Head Cases", is a superhero sitcom created by David and his wife Kathleen and produced by David M. Uslan. The series centers on Thunderhead, a would-be hero whose inability to utilize his ability to produce loud thunderblasts without injury to himself leads him to become a source of comedic derision in the superhero community. The series, which explores events that occur in between the battles typically seen in comic books, was based on a concept originated by Uslan, and partly inspired by "It's Always Sunny in Philadelphia". David describes "Head Cases" as a 75-minute movie divided into 5-minute webisodes. The series will feature guest appearances by other industry personalities, including Stan Lee, who appears as himself, functioning in a similar manner to Norm Peterson from "Cheers".
