During the run of their Adult Swim show, Tim and Eric Awesome Show, Great Job!, the most common allegation made by viewers and critics, was that the duo took advantage of the mentally handicapped when casting their surrealist skits. While much of the show's comedy relies on the unusual personalities of amateur actors, only one of their stable of repeat guests has ever said anything about not being treated professionally. Alien-enthusiast and puppeteer David Liebe Hart has occasionally accused Tim and Eric of neither paying him enough nor taking him on their national tours, but those allegations were dropped pretty quickly when Hart became a regular on Tim and Eric's Check It Out! With Dr. Steve Brule.
The duo do admit to an unusual casting process, saying, "We dig through to the bottom of the pile [of headshots] and find them, then give them lots of lines."
