President Bush is meeting with the Queen of England on a state visit. The conversation turns towards the difficulties in running a country.

The Queen says: "Well, the most important thing is to surround yourself with intelligent people."

Bush frowns and replies: "Well, how do I know the people around me are really intelligent?"

The Queen takes a little sip of tea and says: "Oh, that's easy. You just ask them to answer an intelligence riddle."

The Queen pushes the button on her intercom and says: "Please send Tony Blair in here, would you?"

Blair walks into the room and says: "Yes, Your Majesty?"

The Queen smiles at Blair and says: "Tony, answer me this, please. Your mother and father have a child. It's not your brother and it's not your sister. Who is it?"

Without pausing for a moment, Blair says: "Well, that would be me."

The Queen smiles and says: "Yes! Very good. Thank you!"

Back at the White House, Bush asks to speak with Vice President Dick Cheney. "Hey Dick, answer this for me, would you? Your mother and your father have a child. It's not your brother and it's not your sister. Who is it?"

Cheney frowns and says: "Geez, I'm not sure. Let me get back to you on that one."

Cheney goes to all his advisors and asks everyone he can, but no one can give him an answer. Finally, he ends up in the men's room and recognizes Colin Powell's shoes in the next stall.

Cheney shouts over to him: "Hey Colin! Can you answer this for me? Your mother and father have a child and it's not your brother or your sister. Who is it?"

Powell yells back: "Hey, that's easy. It's me!"

Cheney smiles and yells: "Thanks!"

Cheney goes back to the Oval Office and tells Bush: "Hey, I finally figured out the answer to that riddle! It's Colin Powell!"

Bush gets up and angrily stomps over to Cheney and yells right into Dick's face: "No you idiot! It's Tony Blair!"
