"Did Mom really say that?"
"Choo better believe it."
"Oh, ok." Mike then gasped suddenly. "Uh oh, it seems like we have a dilemma. What are we supposed to do when two of Mom's doctrines are in conflict? It's like when we had to decide which took precedence: 'Whoever smelt it, dealt it' or 'Whoever denied it, supplied it.'"
"Yeah, well, they are both easy. The answer to that one is always "Mike did it," and the answer to this one is, 'Don't eat poison.'"
