Win, Place or Steal (1975)

""Mongo" and the man from M*A*S*H together in the comedy caper of the year!"

Three friends have two things in common: (1) they like to bet on the horses at the track, and (2) they invariably lose. One day they hit upon a scheme to steal one of the track's betting machines, so that they'd be able to print winning tickets and recoup the money they've lost over the years. However, things don't go exactly as planned.
