who played the grandson on mama's family
Mama's Family To fill the void left by Mama's grandchildren, Allan Kayser was cast as Thelma's delinquent teenage grandson Mitchel "Bubba" Higgins. Bubba was the son of Ed and Eunice. Bubba was ordered to live with his grandmother after being released from juvenile hall and placed on probation. Also added to the cast was Beverly Archer, who played the new character of Iola Boylen, the family's wildly quirky and prissy neighbor and Mama's best friend. Her catchphrase was calling out "Knock, knock!" in place of ringing the doorbell.
