Last night NBC premiered Perfect Couples, the peacock's new sitcom about three imperfect couples, which will return in January as part of its three-hour Thursday night comedy block. The episode got off to a strong start, not so much thanks to jokes about how you shouldn't tell your partner to drink diet soda (which, you know, don't do that), but to a very catchy theme song penned by the New Pornographers' power-pop master A.C. Newman. Newman wrote the song specifically for the show, so he's sure doing his part to resuscitate the floundering form — theme songs these days are usually nonexistent, short and instrumental, or preexisting pop songs. The lyrics go, "The secret to the life you wanted / It’s all true / Someone's got to do it / Now we have the facets working / we’ve got through / all we need is you" (though we're not totally sure about those fourth and fifth lines. Thoughts?), so it's not quite "Everybody Knows Your Name," but, still, very nice.
