Continuity mistake: When Mr Burns and Smithers are standing outside Springfield Stadium, Mr Burns says to Smithers, "Put a little smile on his card" and Smithers is writing it down with a pencil in his left hand. When the Simpsons arrive in the next shot, the pencil has changed into another piece of paper.
Continuity mistake: When Homer is starting to go crazy and Ned's face has all the eyes, you can see Jasper in a blue tent. Homer runs away from Ned, going past Jasper's tent, up to a crowd of people...which includes Jasper.Dan23
