While I never myself watched Seinfeld, I thought this was great. It was just great to see this stupid animation. I love how it's all intentional. You got the voices down perfectly in this. The only way to improve it is to make it...about something. I'm just kidding.
I think it's great to compare a slice of life story to a weird fantasy world. It really puts everything in perspective. The facial expressions were great too. It's pretty much what you'd expect from a Mario Seinfeld combination. It's just so funny.
