Obscurity factor: 10
This hour long variety series was a hybrid of variety show and sitcom, with Mary playing Mary McKinnon. McKinnon was the host of her own show at CBS and episodes revolved around her production staff and her home life. Each episode featured a star who was to be a guest on the show within a show and a situation to be dealt with, such as in the episode below, the southern California fires threatening Mary's home. Look for turns by Dodie Goodman, Joyce Van Patten and Michael Keaton, and this episode's special guest, Dick Van Dyke.
This series, nor the one preceding it (Mary! 1978/79) have made it to DVD, but you can find clips on YouTube. Above is part one of the episode featuring Dick Van Dyke.
