A visiting professor at the University of Montana 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.

“That's fantastic. But let me ask you one question further... Have any of you ever made love to a ghost?” asks the professor.

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 replies with a nod and begins to make his way up to the podium.

The professor asks, “Well, tell us what it's like to have sex with a ghost.”

The student replies, “Ghost?!?” Dang, I thought you said ‘goats.’
