I heard this one today at lunch...

Donald Rumsfeld walks into President Bush's office and tells him that two Brazilian people died in Iraq today.

The President bursts into tears.

"Mr. President," says Rumsfeld in confusion, "what happened today is a great tragedy, yes, but we get a lot of bad news in this office. In the past I've had to give you news of dozens of Americans dying in Iraq. What is it you find so moving about today's events?"

And the President says, "Um... how many is a Brazillion, again?"
