Marge: Bart, here's a letter from your school.
Bart: A fire? I didn't start a fire in the teachers' lounge! I mean, what fire? I mean, a letter from school? Please elaborate.
Marge: Someone at your school has a life-threating peanut allergy.
Bart: Cool! Who is it?
Marge: Ah, the letter doesn't say. But from now on, no peanut products are allowed on school property.
(Marge examines Bart's lunch box.)
Marge: Hmm, let's see what you've got. Peanut butter and jelly sandwich, trail mix, starring peanuts. Good grief, more peanuts!
