First appearance of Ruth Cohen as the later self named cashier Ruthie Cohen in the diner Monk's. Ruth would go on to become the most frequent character on the show besides the main four, due to that she was present in basically every scene at Monk's from this episode and forward, although not always seen, depending on what camera angles were used in the diner. She however only received on-screen credit a few times, when she had a couple of lines of dialogue during the last seasons.
The woman next to Kramer in the exercise video scene is Michael Richards' then girlfriend, Ann Talman.
Kramer's (Michael Richards) approach of Fred Savage was inspired by a real experience of writer Larry Charles. Charles once approached Richard Dreyfuss in a bookstore to pitch a script. According to Charles: "I was so excited I started to hyperventilate. I said, 'Don't be scared of me.'"
The hotel that Kramer (Michael Richards) stays at in Hollywood is the same hotel that Julia Roberts stayed at in Pretty Woman (1990) two years previously, a movie that costarred Seinfeld's Jason Alexander.
