I hope you are sitting down because I may have some shocking news for you...
Seinfeld is a TV show, specifically a situation comedy. It is not real despite being the greatest sitcom ever.
It was also filmed in Los Angeles and not NYC.
Sorry, do we need to talk about Santa and Easter Bunny too?
Excuse me! Jerry Seinfeld is a real person! I saw him in person once and he was just like he is on TV!
