Seinfeld i think is meant to be the "Mac Guy" and Bill the "PC Guy" in microsofts version of the PC/Mac Guy ads Seinfeld is the idiot and Bill is the practical smart guy eg. i cant remember it word for word but - "Have you tried taking a shower in your clothes, you can just get in take a shower then go off to work without having to put your clothes back on", PC Guy says "umm??, No" The Mac guy(Seinfeld) in the ad thinks he's smart because it's simple but he's practically stupid, i mean come on if you take a shower your clothes will get wet and you'll look like an idiot. Also Seinfled "Is that your foot", Bill "No it's leather" - Bill is being a smart ass
In this ad:
Mac Guy - Simple Minded, Idiotic, looks up to the PC Guy as a hero/god
PC Guy - Highly Intelligent, Practically Minded
