While visiting England, George Bush is invited to tea with the Queen. He asks her what her leadership philosophy is. She says that it is to surround herself with intelligent people.
Bush asks how she knows if they're intelligent.
"I ask them a riddle," says the Queen. "Allow me to demonstrate."
Bush watches as the Queen summons Tony Blair and asks, "Prime Minister, please answer this question: your mother has a child, and your father has a child, and this child is not your brother or sister. Who is it?"
Tony Blair responds, "I imagine it's me, ma'am."
"Correct. Thank you and good-bye, sir," says the Queen.
Bush is very impressed, so, upon returning to Washington, he decides to test his own entourage. He summons Dick Cheney, and says, "Vice President, I wonder if you can answer a question for me."
"Why, of course, sir. What's on your mind?"
Bush poses the question: "Uhh, your mother has a child, and your father has a child, and this child is not your brother or your sister. Who is it?"
Cheney say, "Mr. President, can you give me one hour?"
Bush agrees, and Cheney leaves. He immediately starts asking different people the question, but nobody can come up with an answer. Finally, with about five minutes left on the clock, Cheney, having lost all hope, goes to the bathroom, where he spots Colin Powell's shoes under the door of one of the stalls.
"Powell, you gotta help me. President gave me this riddle: your mother has a child, and your father has a child, and this child is not your brother or your sister. Who is it?"
Powell answers immediately, "It's me, of course, you dumb***"
Much relieved, Cheney rushes back to the White House, finds George Bush, and exclaims, "I know the answer, sir! It's Colin Powell!"
"Wrong, you dumb***," Bush replies -� "it's Tony Blair!"
