I rented MJ&S a few years back before the indie video store got run out of business. It's actually a pretty good mix of comedy and drama about a private ambulance company, captures a little bit of what Bringing Out The Dead did. I've heard it called the only good movie Bill Cosby made.
Cos is Mother, Racquel Welch is Jugs the dispatcher, and Harvey Keitel is Speed the ambulance driver. Also has Dick Butkus and a pre-Dallas Larry Hagman. IIRC it was a Fox movie, maybe I should drop a line to Mr. Staddon.
