On his first day there, he addressed a student and asked,

"Hey, y'all know where the library is at?"

The student drew himself up to full height and said, "What an ignorant country bumpkin!  You don't know ypu shouldn't end a sentence with a preposition."

Georgia boy says, "You're right.  Let me try again:
Hey, y'all know where the library is at, asshole."

That was what I really wanted to ask Roberts.
