'Davis Rules' (1991)
The plot: In this series premiere, a widowed elementary school principal (Randy Quaid) raises three sons with the help of his wacky dad Gunny Davis (Jonathan Winters). / How many watched: 26.7 million / Touchdown or fumble: Fumble. Despite a strong start, the heartwarming comedy left viewers cold, and ABC yanked it after less than one season. CBS picked it up and added Bonnie Hunt and Giovanni Ribisi, but then pulled the plug six months later.
