The loft in which Pepe and his violin teacher practice is the same setting used previously in "Bedtime Story" when the girls try to catch a train back to Miami but end up meeting a group of clowns. The major difference is that the loft is basically the train station set without all the props except for a piano.
While Sophia helps Pepe train for the fight, she turns up the volume of a recording of what later turns out to be Pepe playing the violin.
The title is from "Fiddler on the Roof" which opened at the Imperial Theater in New York on September 22, 1964 and ran for 3,242 performances, setting a record for the longest running show on Broadway passing "Life With Father" that held the record for 25 years. Bea Arthur was in the original cast.
Chick Vennera guest stars as prizefighter "Kid Pepe". Vennera would guest star two more times playing a completely different character, Enrique Mas - the boss of Betty White's character.
Sophia says that Pepe's acting career will be nothing but playing characters getting arrested on cop shows. For Chick Vennera, who plays Pepe, this is only partially true. Before appearing on The Golden Girls, Vennera appeared as characters on Baretta, The Blue Knight, Vega$, T.J. Hooker, and once as a mugger on Night Court. After his guest appearances on The Golden Girls, he appeared as a one-time character on L.A. Heat. However, contrary to Sophia's prediction about Pepe, Vennera's 35-year career is a diverse portfolio of film, television, and video game roles.
