First dialogue and credited appearance for Ruth Cohen as the self-named cashier Ruthie Cohen at Monk's Diner. At this point Cohen had already been visible as the cashier in over 50 episodes since the Season 4 opening episode (basically every episode which features the diner and uses the across-the-table camera angle that shows the register). Cohen would go on to have a few lines twice more--a credited appearance in one of those episodes--but in total she appeared in 101 episodes, making her by far the most frequent character in the show , besides the main four.
Larry David guest-starred (uncredited) as the newsstand owner who refuses to take George's (Jason Alexander) $20 bill.
Second appearance of Lloyd Braun, after The Non-Fat Yogurt. He is played by a different actor this time, as Peter Keleghan has been replaced by Matt McCoy.
Lloyd Braun, an ABC entertainment executive, lent his name to a character that appears in three episodes throughout the series: Season 5, Episode 7, The Non-Fat Yogurt (1993), this episode, and Season 9, Episode 3, The Serenity Now (1997), and is a neighbor and nemesis of George Costanza (Jason Alexander).
