Story writer Fred Stoller appears in an uncredited cameo as one of the fans behind the gang and the face painter at the hockey game. Sitting next to Fred wearing a Rangers jersey is the "real" Kramer. Viewer Jerry Balsam noticed that there is a character in this episode named Alec Berg, which also happens to be the name of a one of the show's writer-producers. Coincidence? Also there is a visual reference to the fictional company called Gramercy, that Katy Selverstone worked for in a popular series of commercials that she appeared in.
