Seinfeld was a popular TV show that had 9 seasons and 180 episodes. Jerry Seinfeld co-ran it with Larry David for the first seven seasons, producing two dozen episodes per season, which were considered masterpieces due to David's perfectionism. David was overwhelmed with work and didn't realize how big the show was until season 4. When David left, it was challenging for the team to maintain the quality, and they worked without having a day off. David returned to write the finale, where the main characters received their comeuppance.
