In some behind-the-scenes humor, during a scene in Lt. Parker's office, a roster of 'on duty' detectives lists Flint, Arcaro, Manners, Neufeld, and Laszlo. Flint and Arcaro are, of course, the detectives assigned to this current kidnapping. Manners likely is a jest to Sam Manners, who functions as Production Executive on numerous episodes of this series; Neufeld probably kids Assistant Director and Associate Producer Stanley Neufeld; and Laszlo likely refers to Andrew Laszlo, who has been Director of Photography on several episodes of this program.
The statue of the Goddess Athena which was seen in the third season episode The Hot Minerva can be seen in this episode in Matthau's living room.
