While on a case, Baretta phones in a favor to a cop at headquarters (unseen and unheard) named "Stringbean", who only appeared in person on the pilot episode, and was played by Andrew Prine. The character's real name was Andy.
While part of the catch of the series is Baretta going undercover in disguise (carried over from the series Toma), this episode has more than usual. A few of them include an African American pimp, an African American massage therapist, a cowboy and a hippie playing guitar.
