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 do so by asking them the right questions," says the Queen. "Allow me to demonstrate."
Bush watches as the Queen phones Tony Blair and says, "Mr. 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, "It's me, ma'am."
"Correct. Thank you and good-bye, sir," says the Queen. She hangs up and says, "Did you get that, Mr. Bush?"
Bush nods: "Yes ma'am. Thanks a lot. I'll definitely be using that!"
Bush, upon returning to Washington, decides he'd better put the Chairman of the Senate Foreign Relations Committee to the test. Bush summons Dick Lugar to the White House and says, "Senator Lugar, 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?"
Lugar hems and haws and finally asks, "Can I think about it and get back to you?"
Bush agrees, and Lugar leaves. He immediately calls a meeting of other senior Republican senators, and they puzzle over the question for several hours, but nobody can come up with an answer. Finally, in desperation, Lugar calls Rice at the State Department and explains his problem.
"Now lookee here, your mother has a child, and your father has a child, and this child is not your brother or your sister. Who is it?"
Rice answers immediately, "It's me, of course."
Much relieved, Lugar rushes back to the White House, finds George Bush, and exclaims, "I know the answer, sir! I know who it is! It's Condoleezza Rice!"
And Bush replies in disgust, "Wrong, you dumb shit, it's Tony Blair!"
