This is Bitty Schram's last appearance as a regular cast member. Upon completion, Schram left the show and her character was written out of the series.
Monk uses the phrase "Smoke em if you got em." Tony Shalhoub used the same phrase in Men in Black 2 (2002) when he played Jeebs.
There are two characters called "Salvatore" in this episode: one of the police officers and the salesman in Rocket Burger. The salesman is only credited as "Salesman" but he introduces himself to Monk as Salvatore.
