Why does everyone have to pick out the problems in all Seinfeld episodes? I wish ppl wouldn't post this stuff because no one knows what they're talkin about. Oh yea the nameless woman is "Delores" it is clearified in a later episodes.
Also Jerry's mom sending him a check was a joke on its own, jerry did not wave the check at the cockfight. Reason number one: It was a check! who waves a check at a cock fight? George would most likely have NOT been put in jail for aiding a know criminal. Elaine's bf got put in jail because he started a fight.
And its a sitcom! Things happen that are funny! They are not neccessarily real. Its a TV Show so continuity does not HAVE to apply. however most episodes do fit together nicely.
