Seen Ghosts?

A visiting professor at Texas A & M University 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?"
Three 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 his 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 replies with a nod and a grin, and begins to make his way up to the podium. The professor says,

"Well, tell us what it's like to make love with a ghost."
The student replies, "Ghost? ****..... From back there I thought you said, 'Goats'!"
