A brotherly tiff between Mel and Reggie threatens to ruin Malena's first Mother's Day dinner for her mother-in-law -- a feast for which the clueless cook has enlisted Reggie and Sheri's culinary skills. When the guys argue about ownership of a prized Reggie Jackson baseball, Reggie bails on the dinner, leaving Malena to fend for herself. Meanwhile, anxiety also consumes Bobby, who is convinced that Mrs. Ellis disapproves of her, and Dean's special Mother's Day gift goes up in ashes with Sheri's flaming dessert.
