2x12 - The Cosby Show

Theo's math teacher comes for dinner, to Theo's extreme consternation. He thinks she plans to tell his parents of a bad grade on a math test. To his surprise, Mrs. Westlake comes to dinner looking young, attractive, and even with a sense of humor; and she has a very good surprise! Mrs. Westlake also gives Theo his test-he actually gets an 89, and he proceeds to embrace her, much to his shock. Sonia Braga as Mrs. Westlake.
