Titus is an American dark-comedy sitcom. The series was created by its star, Christopher Titus , Jack Kenny, and Brian Hargrove. This sitcom was based on Christopher's stand-up comedy act, which was based loosely upon his real-life family. Titus plays an outwardly childish adult (based on himself), who owns a custom car shop. The show follows him and his dimwitted stepbrother Dave, his girlfriend Erin with the "heart of gold", his goody-goody friend Tommy, and his arrogantly lewd, bigoted and multiple-divorced father Ken "Papa" Titus
