Bush's Parrot

Bush's parrot is asleep on his perch; Bush is at his desk staring vacantly into space. Suddenly, the parrot wakes up and cries, 'Here comes Donald Rumsfeld, Secretary of Defense.’
Bush stops working. What goes on? Then the door opens and it's Rumsfeld. So Bush and Rumsfeld start to talk, but the bird interrupts. 'Here come Condoleezza Rice, minister of propaganda.' And, lo and behold, a minute later, it's true.
Bush tells what's going on, but Rumsfeld and Rice think he's kidding. 'Ah, go on, George, it's a trick, you're giving the bird a signal.'
'No, no,' Bush says. 'This bird somehow knows who's coming, and I'll prove it to you. We'll hide in the closet, where the bird can't see me, and wait for the next visitor.' So there they are, in the closet, and the bird starts up again. But this time it just trembles and hides its head under its wing and squawks.
After a minute, the door opens, and it's the Vice-President. He looks around, thinks the office is empty, and goes away. 'All right, people,' the parrot says, 'it's safe to come out now. Cheney is gone.'
