Cosby (1996)

Season 3: Episode 6

When Griffin accompanies Hilton to ""Grandparents Day"" at Jurnee's school and adds his two cents to the science lesson, it quickly becomes apparent that he is a natural at teaching and holding the kids' interest. Who would have thought?? Hilton is thrilled that Griffin has uncovered a talent for this most noble profession, while Erica is more than ticked off when she learns that Griffin achieved a higher GPA than she did in college. At first resistant to the idea of working hard for little pay and loads of responsibility, Griffin is ultimately swept up with the idea of molding the minds of America's young -- heaven help them.
