||President Bush wakes up one morning, looks out of the White House window and sees "The President Sucks" written in the snow in urine. Furious, he calls in the FBI and demands the perpetrators be found. Later that day the FBI agents return.
"Well sir," says the first agent, "the urine has been analysed and it's the Vice President's". Bush goes purple with rage and shouts, "Is that all?"
"Well no sir," says the agent, "It's the First Lady's handwriting."
