Preposition Police

A young man from the deep south was excited to be attending Harvard University. He needed a book from the library but wasn't sure where the library was located. He stopped a short, fat, freckled redhead and asked, "Where's the library at?"

The redhead gasped and started fanning himself with both hands. The young southerner had never seen a case of the vapors, but if he had, he imagined this is what it would look like. The redhead flailed about and finally responded, "Kind sir, here at Harvard we never end our sentences with a preposition. Would you like to try asking the question again?"

The young southerner rubbed his chin, snapped his fingers and said, "Yes, I would. Where's the library at, asshole?"
