This fellow wants to be a proctologist, and he wants to be a really good proctologist, so he decides to go down to the morgue after class at medical school and practice a little. Well, he uncovers the first guy and there is a cork in his behind! He thinks it's a little strange, so he pulls it out and music starts playing! "... On the road again, just can't wait to get on the road again." Our student really freaks out! He runs and gets the morgue attendant and drags the poor guy back to the table. "Look!" he says, and pulls the cork out again, "... On the road again..." The morgue assistant is totally unimpressed. " So what?" he says. "Isn't that the most amazing thing you've ever seen?", the guy asked. "Are you kidding?" says the morgue assistant, "Any ass hole can sing country music!"
