This might have been the quote (thanks to the Springfield Nuclear Power Plant):
You know, I’ve been thinking. Everyone makes peanut butter and jelly sandwiches, but usually the jelly drips out over the sides and the guy’s hands get all sticky. But your jelly stays right in the middle where it’s supposed to. I don’t know how you do it. You’ve just got a gift I guess, and I’ve always thought so, I’ve just never mentioned it. But it’s time you knew how I feel. I don’t believe in keeping feelings bottled up.
