Heh....I thought about posting that one, but couldn't remember the exact wording!
(this one harkens back to the Clinton regiem.....er.....administration)
One day Bill Clinton walks out of the White House and, to his horror, notices a message that someone had peed into a nearby snowbank: the words read "IMPEACH CLINTON!!!"
Furious, he called the head of his Secret Service detail, the directors of the FBI and CIA, and charged them with finding out who it was that had written such a blasphemous statement in the snow.
A week later, the heads of the various departments all returned to the Oval Office.
"Sir, we've got some good news and some bad news concerning the message in the snow," they informed the President.
"Well, good news first!" he cried.
"The good news is, through a complicated DNA analysis of the urine, we've determined that the supplier was none other than Al Gore."
"Treason! I'll have him fired for this!" ranted Clinton. "What's the bad news?"
"Well, sir.....the handwriting is Chelsea's."
