She also spun stories involving her comical “ne’er-do-well” relatives, notably “Uncle Nabob”, his wife “Aunt Ambrosia”, “Lucifer Hucklehead”, “Miss Lizzie Tinkum”, “Doc Payne”, and, of course, her “Brother”, who was simultaneously both slow-witted and wise. She usually closed her monologues with the exit line “I love you so much it hurts!” She also sang comic novelty songs and often danced with Grandpa Jones.
Pearl drew much of her comic material from her hometown of Centerville, which she called Grinders Switch. Grinders Switch was a community just outside Centerville that consisted of little more than a railroad switch. Those who knew her recognized that the characters were largely based on actual Centerville residents. So much traffic resulted from fans and tourists looking for Grinders Switch that the Hickman County Highway Department eventually changed the designation on the “Grinders Switch” road sign to “Hickman Springs Road”.
Cannon portrayed Minnie Pearl for many years on television, first on ABC’s Ozark Jubilee in the late 1950s; then on the long-running television series Hee Haw, both on CBS and the subsequent syndicated version. She made several appearances on NBC’s The Ford Show, Starring Tennessee Ernie Ford. She also appeared as a celebrity panelist on game shows such as Match Game in 1976 and 1978 and Hollywood Squares in 1980. Her last regular performances on national television were on Ralph Emery’s Nashville Now country-music talk show on the former The Nashville Network (TNN) cable channel. With Emery, she performed in a weekly feature, “Let Minnie Steal Your Joke”, in the Minnie Pearl character and read jokes submitted by viewers, with prizes for the best jokes.
Cannon made a cameo appearance in the film Coal Miner’s Daughter, appearing at the Opry as Minnie Pearl.
