In "Easy Money", the doctor suggested Rodney Dangerfield take up a hobby. There's the scene where he's at the kitchen table assembling a ME-109. By the end of the scene, he's so worked up he tries to commit suicide with an X-Acto knife, damages the model, and when leaving the house with Joe Pesci he tells his wife, "Hey, Rose, there's a Messerschmitt in the kitchen. Clean it up, would ya?"
