When the latest sibling war between Vanessa (Tempestt Bledsoe) and Rudy (Keshia Knight Pulliam) escalates into fullscale property damage, dad Cliff (Bill Cosby) orders the girls to shut up, smile and get along. They proceed do just that--but only when their parents are around. Ultimately, Cliff and Clair (Phylicia Rashad) "sentence" the girls to live in the basement until they can stop quarrelling. It takes the scare tactics of brother Theo (Malcolm-Jamal Warner), who convinces his sisters that the Huxtable cellar has been built upon the bones of an ancient graveyard, to resolve the situation with ruthless efficiency!
