Parks and Rec, NBC

It was a shameless tear­jerker, yet it felt earned and authentic – the kind of moment you never expect TV to get right, least of all a network sitcom. Leslie (Amy Poehler) and Ben (Adam Scott) might be warped, but that's why they belong together – Leslie even interrupted Ben for a midproposal make-out. Mazel tov, you crazy kids! (Bonus: In the same episode, Ron Swanson brought his girlfriend's daughters a saw. Oh, l'amour!)
