While working at Gizmonic Institute, Forrester and his assistant, (Dr. Laurence Earhardt from K-01 to the end of Season One, at which point he was replaced by TV's Frank without explanation) sent Joel cheesy movies which he was forced to watch, in order to find a movie that would drive people mad and allow him to take over the world. In response, Joel built several robot friends to keep him company, and keep himself from being driven mad. Joel, Crow T. Robot, and Tom Servo mocked each of the movies they were forced to watch. During Joel's time on "MST3K", Forrester participated in Invention Exchanges with Joel and the 'bots. He would show his invention, then Joel would show his invention.
