Halloween II - Redneck Ghost Story

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!"
