This Canadian sitcom was hastily assembled in 1970 to comply with upcoming Canadian content requirements and had an extremely limited budget for both time and money. 130 episodes of the series were produced, requiring scripts to be recycled from 1940s radio dramas, line mistakes to be kept in the finished product due to time and money constraints, and virtually the entire series shot from one small living-room set. As a result of the poor-quality end product, the series is often considered one of the worst of all time.

I actually watched this, as a kid.
iirc, it aired in the afternoon (on ctv), and with limited channel selection (6 channels), it was the only station not showing a soap opera. It was so brutal (even for a Canadian show), our 12-year-old brains loved it!
