What is it about Nick Offerman that you find so damned alluring? Is it his droll portrayal of Ron Swanson on Parks and Recreation? Perhaps it's the bristly manliness of his mustache? Offerman himself has a theory about his own appeal, and he'll share it with you in this exclusive Vulture video: It all has to do with the Golden Ratio, obviously. Not sure what that means? Press play and let Offerman explain it to you, but be aware that this theory involves both his giant cranium and his nicely shaped posterior, the latter of which is on display in Offerman's comedy Somebody Up There Likes Me, out on DVD today. If you've ever hoped to hear Offerman wax rhapsodic about his own ass at length ... well, we at Vulture are in the dreams-come-true business. Cheers!
