A visiting professor at the University of Alabama is giving a seminar on the supernatural. To get a feel for his audience, he asks: "How many people here believe in ghosts?" About 90 students raise their hands.

"Well that's a good start. Out of those of you who believe in ghosts, do any of you think you've ever seen a ghost?" About 40 students raise their hands.

"That's really good. I'm really glad you take this seriously. Has anyone here ever talked to a ghost?" 15 students raise their hands.

"That's a great response. Has anyone here ever touched a ghost?" 3 students raise their hands.
"That's fantastic. But let me ask you one question further... Have any of you ever made love to a ghost?"

One student in the back raises his hand. The professor is astonished. He takes off glasses, takes a step back, and says, "Son, all the years I've been giving this lecture, no one has ever claimed to have slept with a ghost. You've got to come up here and tell us about your experience."

The redneck student (remember, this is Alabama) replies with a nod and begins to make his way up to the podium.

The professor says, "Well, tell us what it's like to have sex with a Ghost."

The student replies, "Ghost?!? I thought you said 'goats!'"
