It’s no secret that the creators of one of the most successful television shows of all time were huge baseball geeks.
Jerry Seinfeld is an outspoken Mets fan. Show-runner Larry David is known to attend the occasional Dodgers game in Los Angeles (including saving a man from a murder conviction by filming an episode of Curb Your Enthusiasm during an actual game — check out Long Shot on Netflix, if you haven’t seen it). George Constanza spends multiple seasons as an employee of the New York Yankees — with a David-voiced George Steinbrenner being one of the more popular bit roles.
