One summer in college, I worked in the registrar's office, registering all the incoming freshmen. A prof who was a mentor to me was teaching freshmen seminar and asked me to hand pick a class for her. Straight A students, high SATs, whatever. So I did. 15 students, all named Sarah.

Two of my friends have never met each other. Before they spoke I told both of them that the other one was a bit deaf. They shouted at each other for a few minutes before they realized that I'm an a**hole.
