When Patsy tells Rockford she is no longer interested in marrying her fiancé, Rockford responds by saying, "Tricia's wedding didn't cause this big of a stir." He's talking about Patricia Nixon's White House wedding. This was also a bit of an inside joke as Leslie Charleson bears a striking resemblance to Tricia Nixon.
One of many episodes where there is a mob figure, either in person, or by reference, with a name ending with "ette" (Pinette, Frishette, Binette, Gillette, and a few other). In this case, the mob figure is Joseph Minette, and Patsy Fossler's on the run from the Minette crime family.
The Becker's son, Scotty - who's often mentioned but rarely seen (though he will appear - as a grown man, in the The Rockford Files: Godfather Knows Best (1996) reunion movie), is running for president of the 6th grade in this episode.
The first show with a scene in which the LAPD vehicles have blue emergency lights. Prior to this they had either red only or red and amber. This is also the first show where the LAPD vehicles had fully enclosed lightbars rather then separately housed rotating or separately housed front/rear facing lights.
