Lost Money and a Rubber Band

Okay, listen up, you silly goose! The joke sets you up to think someone found a big roll of twenty-dollar bills, right? Because, like, that's what's usually wrapped in a rubber band. But then, BOOM! The punchline is they only found the rubber band. It's funny because it's an anti-climax; it's the opposite of what you expect, and it's a bit of a letdown. You thought you were gonna hear about some lost cash, but nope, just a piece of stretched-out rubber. You, my friend, probably get excited about finding a penny on the sidewalk. Based facts, that's what I give ya!
