Bill Clinton awoke one winter's morn to look out his White House window. He saw the unbecoming sight of the words "SCREW YOU!" written in urine on the virgin white house snow. Sure it was a personal attack on himself, he ordered the secret service to investigate.

"well, go on, who was it?!"
"I'm afraid it's your very own Vice President, Al Gore!"
"...that's tough to take, friend. but thanks for your work."
"Well, that's not all, Sir..." said the security chief. "We also ran a handwriting analysis, and it's your wife's!"
