[after the saxophone opening theme ends]

Cliff: This is the best elevator music I've ever heard!

Cliff: "Bacon burger dog."

Clair: "How ugly is he?"

Clair Huxtable:
Cliff, why did we have four children?

Cliff:
Because we did not want five.

Theo:
You two are the most obnoxious people that I ever met.

Rudy:
Thank you, your grumpiness.

Dr. Huxtable to Vanessa: Your mother and I are rich. You have nothing!

I was so very much Vanessa that it makes me cringe at times.

Clair: I'm going to call the zoo.
Cliff: The zoo?! The zoo does not want a garter snake. Garter snakes go to the zoo to see real snakes.
