The Four Presidents And Oz

THE FOUR PRESIDENTS AND OZ
Four United States Presidents get caught up in a tornado... and off they whirled to the land of OZ
They finally made it to the Emerald City and went to find the Great Wizard.
"What brings the 4 of you before the great Wizard of Oz?"
Jimmy Carter stepped forward timidly and said: "I've come for some courage."
"No Problem!" said the Wizard.
"Who's next?"
Richard Nixon stepped forward, "Well, I think I need a heart."
"Done! says the Wizard. "Who comes next before the Great and Powerful
Oz?"
Up stepped George Bush and said, "I'm told by the American people that I need a brain."
"No problem! said the Wizard. "Consider it done."
Then there is a great silence in the hall. Bill Clinton is just standing there, looking around, but he doesn't say a word.
Irritated, the Wizard finally asks, "Well, what do you want?"
"IS DOROTHY HERE?"
