I LOVE the Cosby Show, but A Different World is my FAVORITE show in the world. At least the ones after Denise left the show. But to answer the questions:
Favorite Cosby Kid: I really liked them all except for Sandra. LAWD she was soooo boring. They really could have left her off in my opinion.
Favorite Non-Cosby Kid: Without a doubt, it was Bud (Kenny). I also like Stanlely, the few times that he was on the show.
Favorite Episode: 1.) When Vanessa lied about being out with that guy (can't remember his name) and Cliff and Clare turned the couch around to wait for her. That's when Cliff put the apples on top of each other. 2.) The "shirt" episode. 3.)The one when Rudy started her period and Clare told Rudy "there would be times when you are GLAD that this happens

"
My Least Favorite: When the men were with child and the fairytale ep. I HATED THOSE!!!! UGH
