A kid from Alabama gets accepted to Harvard. Confused on his first day, he asks an upperclassman, “Excuse me sir. Can you tell me where the library is at?” The upperclassman responds. “I don’t know who you are or how you got here. But this is Harvard, the finest University in the world. We have very high standards. We do not go about ending sentences in prepositions. Rephrase your question.” The new kid says. “Sure thing. Excuse me sir. Can you tell me where the library is at, a$$hole?”
