It feels like the characters in Seinfeld were fully developed and every episode was delightfully packed full of comedy from day one. But if you go back and watch the first season, you'll see there was a bit of figuring out to be done (part of what irks me about streamers gutting shows so quickly these days, but that's a topic for another day).

Nonetheless, Seinfeld grew into one of the greatest sitcoms to ever hit the airwaves. But it was originally known by a different name. I wonder if they had kept the title whether the show would have been as successful? Not sure I want to see what that timeline is like.
