Did you hear about the guy who made the knock-knock joke? I heard he got the Nobel Prize.

Hey, knucklehead, this joke is funny 'cause the Nobel Prize is a super prestigious award, usually for, like, curing cancer or ending wars. Giving it to someone for a dumb knock-knock joke is so unexpected it's hilarious! Which is lost on you because you probably struggle with opening doors, let alone telling jokes.
