The Bishop

A crozier slams down on the desk of the crooked insurance man Mr. Devious, and the moment he cries out the hero's name the action cuts to the titles of a church-produced crime film. In mitre and robes, the Bishop and four hench-vicars in dark glasses screech up to a village church in a huge American car and burst in just as the vicar announces his text, a second too late to stop the pulpit exploding. A call through his crook sends him to a christening where the baby is ticking, then to a wedding where pulling the ring brings down an enormous weight, past a hanged bell-ringer and to a graveside where a cannon rises out of the grave. Finally a faint cry from an office-block window sends the gang sprinting through the streets and up the stairs to Mr. Devious's door, which they smash open using one of the vicars as a battering ram, and the film starts over from the beginning.

Wikipedia's episode list describes the segment as a parody of The Saint scored with Henry Mancini's Peter Gunn theme. The Bishop returns briefly later in the same episode, when a studio discussion cuts back to him and his titles stop abruptly.
