Why did Kramer and George think Jerry's girlfriend was a LOSER? She was attractive and intelligent with a goregous body so just wondering why Kramer and George called her a loser.

I don't know, I don't think it made sense.

I always wondered that myself. But as soon as Jerry's mother liked her,Jerry didn't.

I was wondering the exact same thing. The only thing that I can come up with is that she was way too hot and just seemed way too good for Jerry. Maybe they could tell she was so perfect that it's a parent's dream. Who knows?
