A redneck teacher decides to give her class a small pop quiz around Halloween.
"Okay, how many of you have seen a ghost?" About 30% of the class puts their hand up.
"Okay, how many of you have actually touched a ghost?" About 10% of the class puts their hand up.
"Okay, how many of you have had sex with a ghost?" Dead silence, until a little redneck boy in the back row puts up his hand.
"You've actually had sex with a ghost?"
"Ghost? Oh. I thought you said goat!"
