Off to see the wizard

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 four 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 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 doesnt say a word.
Irritated, the Wizard finally asks,
"Well, what do you want?"

Bill Clinton stepped forward,
"IS DOROTHY HERE?"
