I came across this joke courtesy of Maxine Gentle on the Gordon Gentle Campaign site;
While visiting England, George W. Bush is invited to tea with The Queen.
Mr. Bush asks her majesty what her "real" leadership philosophy is.
HRH replies that it is quite simply to surround herself with intelligent people.
George W. then asks how she knows if they are truly intelligent.
"I usually do so by asking them the right questions," says the Queen.
"Allow me to demonstrate." She then 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 immediately responds ,"Certainly, the child would
be me, ma'am." "Correct. Thank you and good-bye, Mr. Prime Minister,"
says the Queen. She hangs up and says, "Did you get that, George?"
"Yes, your Majesty. Thanks a lot. I'll definitely be using that one!"
Upon returning to Washington, Mr. Bush decides he better put the
Chairman of the Senate Foreign Relations Committee to the test.
He summons Jesse Helms to the White House and says,
"Senator Helms, I wonder if you can answer a question for me."
"Why, of course, George, What's on your mind?""Uhh," says Mr. Bush,
"your mother has a child, and your father has a child, and this child is
not your brother or your sister. Who is it?"
Helms hems and haws and finally asks, "Can I think about it and get back to you?"
Bush agrees, and Helms leaves.
Helms immediately calls a meeting of other senior Republican senators,
and they proceed to puzzle over the question for several hours,
but nobody can come up with an answer.
Finally, in desperation, Helms calls Colin Powell at the State Department and
explains his problem. Senator Helms poses the question
"Now lookee here, son, 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 cracker."
Much relieved, Senator Helms rushes back to the White House and reports,
"It's Colin Powell!" Mr Bush replies in total disgust:
"Wrong, you dumb shit, it's Tony Blair!"
