Not so dumb blonde

A blonde is sitting on a plane next to an annoying, pushy businessmen. The man asks her if she would like to play a game. She politely declines, yet the man explains the game to her anyway.

He says, "It goes like this: I ask you a question and if you get it wrong you give me $5, and vice-versa."

She declines his offer once again, and tries to fall asleep.

The man tries harder, "Aw, come on. I'll give you $50 for each question. Or how about $500?"

At that number, the blonde agrees.

The businessman explains again, "If you get my question wrong you give me $5. And when you ask the question, if I get it wrong, I will pay you $500.

"Got it," she replies.

He asks, "Who was the sixth president?" She admits she doesn't know and gives him $5.

Now it's her turn, and she says, "What has purple legs, five arms and three two yellow teeth?"

The businessman doesn't know - he uses his laptop, checks the Internet, e-mails his friends. No one knows the answer. So he gives her $500.00.

As they're landing he asks her, "What was that thing anyway?"

She thinks a few minutes, hands him $5 and walks off the plane.
