There are so many that is hard to pick one.
First Season-When Clair and the girls go shopping, and Theo tells Cliff's dad that he can't come in because his dad wants to sleep. That was hilarious,and Cliff's dad wants Denise to go to his college.
Second Season-Theo's Holiday when they teach him about the real world.
Third Season-I thought this season was alittle boring since (Rashad) wasn't really in it due to pregency. But I did like the one where they try to fool Cliff by hiding
Sondra's and Elvin's engagement.
Season Four-When Sondra and Elvin come to say that they are not going to be a doctor and Lawyer. And when Cliff asks Clair why is it that he always has to be the calm one. Which is true, when Cliff is upset she makes him be calm but she doesn't have to be that is cute.
Season Five-When Clair tries to lose weight and her real life sister (Allen) is her trainer to get her to lose weight.
Season Six or Seven-What's it all about, when Clair has a burn out and goes out to the cabin for the weekend. And the Olivia and Cliff scene was cute, Olivia: Why did Mrs. Huxtable leave town because she ate to much.
Eight: hmmm...
