The Best TV Couples of All Time

David and Maddie (Bruce Willis and Cybill Shepherd), Moonlighting

When former model Maddie Hayes meets David Addison, the schlub running her detective agency, sparks fly. In fact, they burn the whole damn house down with their sexual tension. They raise will-they-or-won't-they to an artform. And then unfortunately... they did it. The audience fled, the ratings plummeted, and it was forever written in the prime-time rule book that protagonists must never canoodle. Thanks a lot, Dave and Maddie! (We'll always have Blue Moon.)
