First of all, I remember that this Canadian stunt show did not get a wide syndication in the U.S. I was living in Alabama when it started but only got to see it at my grandparents' in North Carolina, where their local ABC affiliate carried it after the news.
Now, as for the show itself. Perhaps by 1971 standards there are few problems; the format of the show is that two teams (men vs. women) choose from a category board occupations related to the opposite gender. Each team performs the stunt connected with the occupation; the team with the least total time after four rounds wins.
So far, so good. But on the one show that's available online, two of the female contestants are housewives, while the third is a keypunch operator. The occupations are things like "chorus girl" and "hairdresser," and are placed on the women's side of the board; the men's side has things like "paperboy." Now in 1971 probably most women had not entered the job market, and today there's really no such thing as a "men's" or "women's" occupation. The concept of men vs. women could still work, but the occupations could not be gender-stereotyped as they were then.
