A Different World (1987) : 4x9

Whitley thrives academically after she begins dating Dwayne, while he gets the first C of his life because he spends all his time fawning over her instead of studying. He dreams that the C is the beginning of a downward spiral; and that he will end up a fat, lazy slob whom Whitley eventually dumps. Whitley wakes him up and offers him cookies, and Dwayne starts yelling and throws her out of the apartment. Crushed, she throws herself into her role as director of Ron and Freddie's video time capsule. Dwayne dreams that he devotes himself to science at the expense of everything else. He wins the Nobel Prize, but is devastated to find that Whitley married someone else. Dwayne apologizes to Whitley and explains his problem.
