Sam: I thought you were on a diet for the formal, Amy.
Amy: I am on a diet. I ate like one chip, what about you!? I thought you were on a diet too?
Amy: You're eating ice-cream!
Sam: It's banana, duh.
My friend (to her brother): Hey Dave, do you want a doughnut?
Dave: Okay, thanks (munching thoughtfully) doughnuts are healthy, aren't they?
My friend: Are you kidding me?
Dave: Well, they have dough and nuts in them... why are you both laughing at me?
