A professor at the University of Kentucky is giving a lecture 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 had sex with a ghost?" One student way 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. As he ambles slowly toward 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 Goat."
