A student decides he wants to be the best proctologist ever, so he goes down to the morgue after class to get some practice. The first corpse he looks at has a cork in his butt! He thinks "that's odd", so he yanks it out and to his amazement, music starts playing.
"...On the road again, I just can't wait to get on the road again..."
The guy flips! He gets the chief coroner and brings him to the table.
"Check this out!" he says, and yanks the cork back out", and sure enough...."On the road again..."
The Coroner looks at him and says "So?"
"So?!! Isn't that the most incredible thing you've ever seen?
"What are you talking about?" says the coroner... "Any ass-hole can sing country music!"
