Does anyone remember the first episode where Jerry's apartment was much smaller and his parents were sleeping on his pull-out sofa? I liked his father very much - he was a great straight-man. They changed fathers right after that, I think. I don't remember if the original Mr. Seinfeld was in more than that one episode.
I sometimes find Jerry's current father more annoying than funny, Does anyone else remember the original father, and would anyone prefer him to the current father?
