Did anyone notice that Roy's ( the dentist that gives Jerry and George the note in the massage episode ) receptionist is the same woman who played the diner waitress in the bubble boy episode( Jerry autographs a picture for her and then asks for it back, and she refuses.)
Alos, in "Working", a sitcom on last night, besides "Banya" who has a regular role on the series, the guy who played George's potential employer on the episode with the noisy suit and Elaine's doppelganger mannequin had a guest appearance as a snooty upper level manager. He even exhorts someone to be more of a team player, as he told George to eat some of the poisoned pie and be part of the team.
