Like I needed another reason to adore January Jones. On last night’s Jimmy Fallon, the host challenged the Mad Men beauty to a friendly game of beer-pong. Even though she lost (a staggering upset, considering Fallon’s 1-5 overall record against the likes of Ivanka Trump and Betty White), she won points for belittling Fallon’s watered-down version of the sport. January Jones knows her some beer-pong.

Jones is a Midwesterner, probably more like the Milwaukee gal who was enamored with British accents in Love, Actually than the icy Betty Draper. If her upcoming appearance on Saturday Night Live wasn’t already a must-see, her pong-IQ clinched it.

Which arm of yours would you happily gnaw off to play January Jones in beer-pong?
