[The brothers have covered the entire kitchen floor in baited mousetraps]

Lars:
Don't you think this is a little... much?

Ernie:
Never underestimate your opponent. Let's say, he has mastered a way to empty a mousetrap without getting caught. If he snaps one of these babies, the chain reaction will start snapping them all. He'll panic, and the law of averages says that one of them has to nab him.

Lars:
That's pretty smart.

Ernie:
Yeah, well, I like to use both sides of my brain.
