The scene from The Social Network, which showed off Jesse Eisenberg's best pouty face, was bound to spawn a meme. Hell, any scene with Jesse Eisenberg making a pouty face is pure comedy, but only one had the potential to become a first class meme.
The exchange between Mark and the girl in lecture hall is the perfect palette to make some magic. Just think of the things you could have that note say!
"I just joined Google+."
"You look like Michael Cera."
The possibilities are endless! I've provided the blank meme above, now show me your best gorilla face.
