The Cosby Show (1984)

S1E6 Breaking With Tradition

When Cliff's father, Russell, comes to visit, he starts probing Cliff about the children's college plans. He brings up Hillman, the school he and Cliff attended, and turns to Denise for her opinion. Initially resistant to the idea, Denise changes her stance when Russell reveals that the male-to-female ratio is favorable. This marks the first appearance of Earle Hyman as Russell Huxtable, Cliff's father.
