Mary says that Frankie "got some 'splaining to do"
Mary says in voiceover: "I really wanted to turn around and pop off one of those Columbo questions -- you know, the innocuous afterthought that lets the killer know that I know he did it: [imitating Peter Falk]: 'Excuse me, do you always where white shoes after Labor Day?'"
Frankie says sarcastically that Mary is "the amazing frigging Kreskin" and Mary replies "I have no idea who that is"
Mann says "yes, Fredo" imitating an Italian accent to refer to the Mafia
In order to deceive a suspect, Mary adopts a sexy voice on the telephone and says her name is Nomi, then afterward she explains that she got the name from "Showgirls".
