I don't know, I was thinking it was brilliant! Now I'm trying to figure out who has an 8-year-old I can borrow to plant in my classes with all the answers to my questions.
Probably highly paraphrased from the original, which I read many years ago on some website I can't recall...
Two university math professors are having lunch at a diner one day, and arguing about the state of youth, and how little "kids know today". One of the esteemed gentlemen (Professor B) goes to the washroom, and his dining companion, Professor A, waves the young waitress over.
Prof A: "Young lady, I'll give you $10 if you'll do me this favour. When my friend comes back, I'd like you to respond 'x squared' when I ask you a math question"
Waitress: "Ex Squared when you ask me a math question. No problem!"
Professor A gives her the $10, and shortly thereafter, Professor B comes back, he and Professor A continue conversing for a while. Finally, Professor A proposes a wager.
Prof A: "I think the youth know more than you give them credit for. I'll bet you $20 that when I ask our waitress a simple calculus question, she'll be able to give the correct answer."
Professor B agrees, and Professor A beckons their waitress over.
Prof A: "Miss, could you tell me what the integral of 2 x is?"
Waitress: "Why certainly, it's x^2!"
Prof. A: "See? What'd I tell you?"
Waitress: "Oh, plus a constant!"
