Nibbler: Fry, do you remember some months ago when the Earth was attacked by flying brains?
Fry: Hmm, I remember the square dancing stomachs, although that might have been a milanta commerical. Wait! The brains! I do remember! But no one else does. They said I was crazy.
Male Nibblonian: On the contrary. You remember beause you were the only one immune to the brain's mental attack.
Fry: Because I'm so smart?
