On the plane, Monahan makes a joke that had he known he'd be taking a flight he'd have brought a toothbrush and pair of socks. Deliberate or not, this resembles a situation in the Odd Couple, a show that starred Klugman and often featured Garry Walberg, who here plays Lt. Monahan. Felix once was appalled that Oscar took an overnight plane flight without any luggage to which Oscar said he didn't need any luggage. Felix asked why he didn't even take a change of socks? Oscar takes a pair of socks out of his pocket. Felix asks what about a toothbrush? Oscar says it's inside the rolled up socks. Monahan's line was dubbed in on a voiceover, apparently it was thought of after the fact.
