"How much would could a woodchuck chuck if a woodchuck could chuck wood?"
"A woodchuck could chuck no amount of wood, because a wood chuck can't chuck wood."
"But if that woodchuck could chuck, and would chuck, some amount of wood, how much wood could that woodchuck chuck?"
"Even if a woodchuck could chuck wood, and even if a woodchuck would chuck wood, should a woodchuck chuck wood?"
"A woodchuck should chuck if a woodchuck could chuck wood, as long as a woodchuck would chuck wood."
"Oh, shut up."
