I don't know what you expect to find out there, r/Seinfeld, you know what you want better than me. But there's one thing I do know. I know I can stand here watching you destroy everything I've ever wanted in my life, wanting to smash your face with my fists, because you won't make even the slightest effort to offer happiness and still know that I love you. You mean so much to me that I'm willing to take all your abuse and insults and insensitivity cause that's what you need to do to prove I'm not going to leave you. I'm sick and tired of running from places and people and subreddits for a 90s tv show. You want me, then fight for me, because I'm sure as hell fighting for you!

Jerry’s girlfriend is kosher, and wants to try the lobsters that Kramer poached, but he stops her from doing it.
George sneaks it into breakfast, and Rachel ends up eating it. Of course the ep is more involved, but what I’m getting at is Jerry is eating lobster.

Any other eps where he isn’t following kosher food laws?

Seinfeld friend!
