Oh, Nun is the fourteenth episode of Season 6 of Three's Company, and the 114th overall episode of the series. Written by Calvin Kelly and directed by Dave Powers, it first aired 19 January 1982 on ABC.


Jack is attracted to Terri's high school friend Catherine, who comes to visit. It turns out that she is a nun, but things are patched up and Jack and Catherine even do some sightseeing together. Jack overhears Catherine reading a letter to Terri and mistakenly believes that Catherine is leaving the convent to marry him.

Larry and Jack then cook up a scheme where Jack pretends to be an alcoholic and hangs out at a sleazy bar, so that Catherine will lose interest in him. Janet and Mr. Furley soon become involved in a big scene at the bar before the whole mess is straightened out by Catherine and her father, a police Captain.
