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.

?Well that's a good start,? says the professor, ?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,? continues the professor, ?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,? remarks the impressed professor, ?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?? 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.?
