Season 5: Episode 111: Cliff Babysits
Russell gets eight tickets to the sold-out Michael Jackson concert from a friend. They are one ticket short of being able to take the whole family, so Clair suggests that she and Cliff babysit and let Sondra and Elvin go to the show. Kenny takes the extra ticket. Elvin is afraid to leave the twins for an evening, but Sondra convinces him that they need to get out. Kenny becomes jealous when Rudy pays extra attention to her appearance in the hopes of attracting Michael. Kenny accuses her of failing to recognize that Kenny is the "real thing," and vows to leave her for Whitney Houston. Clair has to go to work to deal with an emergency after another lawyer becomes ill, leaving Cliff alone with Nelson and Winnie. He tries his best to keep them entertained. He tells them a story about his brother, James Theodore Huxtable, who died of rheumatic fever at the age of seven.
