Two mathematicians went out to lunch. Over lunch, one complained that most people don't understand even basic math. The other took a more optimistic view. A short time later, while the pessimist was in the bathroom, the other called the waitress over. "I am going to call you over in a few minutes," he explained, "and I am going to ask you a question. I want you to answer X3/3. OK?"....When the pessimist came back, he called the waitress over. "Look, I'll prove people understand math better than you think. OK, young lady, what is the integral of X2?"... "X3/3" she slowly repeated and walked away. Then she turned around and said,
"Plus a constant."
