<P> 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 . </P>
