Preposition Jokes

IN America's dozen Ivy League Universities, on top of the list come Yale and Harvard or perhaps Harvard followed by Yale. By and large America does not have an upper class accent distinct from that of commoners as is heard in England. The only exception is Harvard which has imbibed some of Boston's
Brahmanical air of superiority by its distinct upper class speech.

This one is told of a freshman who asked a senior student: "Can you tell me where the library is at?"

The senior snubbed him, "At Harvard, we never end a sentence with a preposition."

The freshman had a second go: "Can you tell me where the library is at, you asshole?"

A gentleman wanders around the campus of a school looking for the library. He approaches a student and asked, "Excuse me young man. Would you be good enough and tell me where the library is at?"
The student, in a very arrogant and belittling tone, replied, "I sorry, sir, but at this school, we are taught never to end a sentence with a preposition!"
The gentleman smiled, and in a very apologetic tone replied, "I beg your pardon. Please allow me to rephrase my question. Would you be good enough to tell me where the library is at, asshole?"

A preposition is a bad thing to end a sentence with.
And a conjunction is a bad thing to begin a sentence with.

Never use a preposition to end a sentence with.
