Person A and Person B were introduced to each other at a party. Upon learning that Person A was a mathematician, Person B said, "Oh, I've heard that mathematicians are difficult to get along with."

To this, Person A immediately replied, "Certainly not! In fact, I have this friend who is both a mathematician and very easy to get along with. He is so easy going that he has hundreds of friends, and he never gets into arguments. Thus, by this counterexample, we see that your assertion that mathematicians are difficult to get along with is utterly false."
