If there are three things I've learned about [people who are attracted to men], it's that they love a) dudes who play guitar, b) dudes who pull off the perfectly-loosened tie and rolled-up sleeves look, and c) dudes who are Joseph Gordon-Levitt. Behold: I bring you all three, in this video from a Sundance event last night. Please watch, swoon, and most importantly, share with all your friends.
