As Jim and Falcone are leaving Angie's house, Jim tells Augie to be careful in the sun and Augie replies "yeah uh uh I'll put iodine in the baby oil!" The iodine and baby oil mixture was still popular in the 70's as a way of getting a darker tan, however the mixture can be very harmful to the skin as it attracts UV Rays a lot more and the penetrate deeper into the skin and cause damage.
Hector Elizondo also played Rockford's old war buddy John Micelli, in the 1st season episode, Say Goodbye to Jennifer (1975).
The TV character of Falcone - being based upon a 'real' cop (in this case the fictitious Frank Falcone'), is very similar to the TV show's ' Toma (1973) (and the re-worked, re-cast iteration; Baretta (1975)) being based on a real cop; Frank Serpico. NYPD officer, Serpico had just been the focus of the eponymous film Serpico (1973), with Al Pacino playing him). It's given a very tongue-in-cheek nudge in the opening scene, when Rocky's over at Jim's watching the show, Falcone. It's opening - a take-off 'of the 'real, grittiness' of them (with squealing tires, car crashes), and then the pouty 'Falcone', or as Jim reminds everyone -'an actor playing him', comes on and give the (Falcone series') trademark line; 'freeze, turkey'.
