John McCain's primary qualifications for the presidency are that he's old, he was tortured, and he's been a corrupt Senator for hundreds of years. Also he'd like you to know that he has a sense of humor, which is why he's The Daily Show's most-invited guest ever. On the show last night, McCain once again demonstrated how "hip" and "with it" he is by naming a character on a popular sitcom. One that is currently on-air, even! Not, like, Maynard G. Krebs or something. Jon Stewart desperately tried to get him to appear more presidential by making a joke he knew McCain wouldn't play along with.
