Dimwit Dexter (originally called Dumb Like Dee Dee) is the fourth pilot episode of Dexter's Laboratory. It first aired on April 14, 1996 and later re-aired on May 26, 1996 as part of the third part of episode 5 in season 1. In this episode, Dexter's brain shuts down as a result of him overworking, which leads to him behaving erratically and being the butt of jokes among Dee Dee and the entire neighborhood.
When this episode aired on The Cartoon Cartoon Show, the Cartoon Cartoons theme played over the title card instead of the original music.
This episode was originally going to be called "Dumb Like Dee Dee".
