Be careful not just of what but of how you wish

Bill Clinton, Al Gore, and George W. Bush went to a fitness spa. After
lunch, all three went to the men's room, where they found a strange-looking
gent sitting at the entrance.

He said, "Welcome to the gentlemen's room. Be sure to check out our newest
feature, a mirror that, if you look into it and say something truthful, you
will be rewarded by having a wish granted But, he warned, if you say
something FALSE you will be sucked into the mirror to live in a void of
nothingness for all eternity.

The three men quickly entered and upon finding the mirror, Bill Clinton
stepped up and said, "I think I'm the raunchiest of us three," and he
suddenly found the keys to a brand new Bentley in his hands.

Al Gore stepped up and said, "I think that of the three of us I am the most
aware of the environmental problems of the world," and in an instant he was
surrounded by a pile of money to fund his next presidential campaign.

Excited over the possibility of having a wish come true, George W. Bush
looked into the mirror and said, "I think..."

and was promptly sucked into the mirror.
