I just saw a new Get a Mac ad while watching Two and a Half Men on CBS. In the ad, PC has a security guard dressed in a black suit with a headset. Everytime either Mac or PC says something, the guard will say "PC, Mac has a question (etc.), allow or deny?". This goes on until the whole commercial until the PC states "I can turn it off but that would defeat the purpose..." and the guard goes "You have come to a sad realization, accept or deny?"
