It was sort of a serendipitous timing yesterday when I came across one of those retro tv stations and right at the moment, a cheating man got his due comings from "the" women. Then i had to stop and think back in the 70's & 80's. If in a show/sitcom a guy was cheating, (or thought to be cheating) he would always get caught and invariably have something dumped over his head, especially if they were in a restaurant or he was going to meet in a restaurant...you always knew his fate...
i listed a few of the many examples that are out there. Most are towards the end because that's when they would get caught.
