(Elvin wants to ask Cliff and Clair questions about child rearing)
Cliff: (to Clair) A little child-rearing Q&A? He's lucky I'm not gonna Q his A!
(After Sondra and Clair have a conversation loaded with laywer terminology)
Cliff: So, Elvin...the shin bone connected to the knee bone.
Sondra: We can't die. We are too far in debt to die.
Theo: So this means you don't need me?
Elvin: No no no, the opposite. You are our will to live!
Cliff: (sitting down on Rudy's low bed) Whoa...anti-old-people bed!
Clair: Cliff, they're here.
Cliff: Who is here?
Clair: The moody Rudy blues!
Rudy gives Cliff a "Zerbert" (something she used to do in her earlier years), the last one she does in the series.
Lance and Charmaine stop by the Huxtable house before heading off for a visit to Hillman College. Their visit was the subplot on that night's episode of A Different World.
