Donald Rumsfeld briefed the president this morning.
He told Bush that three brazilian soldiers had been killed in Iraq.
To everyones amazement, all of the colour ran from bush's face, then he collapsed onto his desk, head in hands, visibly shaken, almost whimpering.
Finaly he composed himself and asked Rumsfeld "Just exactly how many is a Brazillion?"
