A professor at the University of Missouri was giving a lecture on the super-natural.
To get a feel for his audience, he asked, "How many people here believe in ghosts?"
About 90 students raised their hands.
"Well, that's a good start. Out of those of you who believe in ghosts, do any of you think you have seen a ghost?"
About 40 students raised their hands.
"That's really good. I'm really glad you take this seriously. Has anyone here ever talked to a ghost?"
About 15 students raised their hand.
"Has anyone here ever touched a ghost?"
Three students raised their hands.
"That's fantastic. Now let me ask you one question further...Have any of you ever had a sexual experience with a ghost?"
Way in the back, Jethro raised his hand.
The professor takes off his glasses, and says "Son, all the years I've been giving this lecture, no one has ever claimed to have had sex with a ghost. You've got to come up here and tell us about your experience."
The big redneck student replied with a nod and a grin, and began to make his way up to the podium. When he reached the front of the room, the professor asks, "So, Jethro, tell us what it's like to have sex with a ghost."
Jethro replied, "S*$&@)T !! From way back thar I thought you said goats!"
