It was the first day of the new term at Princeton, and a black freshman was learning his way around the campus. Stopping a distinguished looking upperclassman, he enquired, “Say, can you tell me where the library is at?”
“My good fellow,” came the reply, “at Princeton we do not end our sentence with a preposition.”
“All right,” said the freshman, “can you tell me where the library is at, asshole?”
