An actual episode of the 1950s western show "The Cisco Kid" is shown with dubbed voices.
While this is one of the lesser episodes, it does have some funny moments. The plot seems to be some bank robbers using some kind of knock out gas on the bank employees and customers. The only SCTV voice is Martin Short, though he did not become a cast member until the NBC years. Steven Kampmann (he would later be Kirk on the "Newhart" show) does other voices and some writing. Short has some funny moments as excitable sidekick Pancho. Kampmann does a Mickey Mouse type voice for a character who looks like Alan Ladd (a running joke in the show).
