One of many episodes where there is a mob figure, either in person, or by reference, with a name ending with "ette". In this case, the mob figure is Joseph Minette, and is mentioned by the character of Patsy Fossler, who is on the run from the Minette Crime Family. There have also been mob characters named Pinette, Frishette, Binette, Gillette, and a few others.
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 is 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.
