Quote from Denise in the episode Spoiler: Bert Gets Married
Denise: Wait, you find messages in bear shit? Droppings Reader: Oh, yes. When will the rains come? Will our women be fertile? Stuart: Of course. Primitive cultures, signs in animal droppings. Mind if I jump in? Denise: What are you doing? Stuart: If we're gonna receive a message in this universe, maybe this is how. Denise: In shit? Stuart: I don't make the rules, Denise. Now, you wanna help me, or you wanna stand there looking disgusted? Denise: Oh, disgusted, no question.
