Actually, President Bush isn't a real character. He's a CGI image created in a joint venture by the CIA and the Mossad. Next season... sorry... next
term, he's going to be able to fly without the need for Air Force one.
The entire first family and most of the cabinet are all computer generated as well. What, you think real people look that good?
Oddly enough, his dog "Spot," is a real character. But his real name is Fido.
