A student of proctology is in the morgue one day after classes, wanting to get a little practice in before the final exams. He goes over to a table where a body is lying face down. He uncovers the body and, to his surprise, he finds a cork in the corpse's rectum.

Figuring that this is fairly unusual, he pulls the cork out and, to his absolute surprise, music begins playing: "On the road again...just can't wait to get on the road again..."

The student is amazed, and pops the cork back into the anus. The music stops.
Totally freaked out, the student calls the Medical Examiner over to the corpse.
"Look at this, this is really something," the student tells the examiner as he pulls the cork back out again. They hear: "On the road again...just can't wait to get on the road again..."

"So what?" the Medical Examiner replies, obviously unimpressed with the student's discovery.
"But isn't that the most amazing thing you've ever seen?" asked the student.
"Are you kidding?" replied the examiner, "Any asshole can sing country music."
