Actor Allusion: In the very first line of the show's theme song "The Unknown Stuntman" (sung by Lee Majors himself): "Well, I'm not the kind to kiss and tell, but I've been seen with Farrah..."
In one episode, Colt uses a small catapult to jump over a fence in much the same way Lee Majors (or rather his stuntman) simulated bionic jumping as Steve Austin in The Six Million Dollar Man.
Hey, It's That Guy!: Terri Shannon, Colt's boss during the second through fourth seasons, is played by Markie Post, who would go on to greater '80s fame as Christine Sullivan on Night Court.
Colt's first-season boss, "Big Jack", is played by Jo Ann Plug, better known as Lt. Dish in the M*A*S*H movie.
This also applies to people working off camera as well. Theme song co-composer Dave Somerville had previously been lead vocalist with The Diamonds, a late '50s/early '60s vocal quartet from Canada mostly well known for interpreting and introducing rhythm and blues vocal group music to the wider pop music audience. Their hits include Little Darlin' and The Stroll.
