My friends and I are learning the dance to Super Junior's Sexy, Free & Single, so naturally we were watching the music video when we happened, randomly, upon this screen shot.

Isn't it entirely meme worthy?
I was thinking, "Why so serious?", or, "I kill you", would be fun as a meme for this particular picture. I think you folks can probably think of some of your own. Maybe they will be better than the ones I thought up.
