As the President is getting off the helicopter on the White House lawn, he has a baby pig under each arm.
The Marine guard snaps to attention, salutes, and says: "Sir, nice pigs, sir!"
The President replies: "These are not pigs, these are authentic Texan Razorback Hogs. I got one for VP Cheney, and I got one for Defense Secretary Rumsfeld."
The Marine again snaps to attention, salutes, and replies, "Sir,nice trade, sir!"
