Aviators Change You.

In Youth in Revolt, Cera plays Nick Twisp, an intellectually sophisticated, yet unlucky-in-love high schooler (hmm sounds familiar still) with the hots for a pretty girl he meets over the summer. To muster up the courage to woo her, he imagines a mustachioed alter-ego named François Dillinger who has no problems seducing the ladies. (That’s Cera as Twisp and Dillinger in the picture above.)

It got strong reviews out of Toronto, and maybe-just maybe- Dillinger is the farthest is the farthest thing from George-Michael Bluth that Cera has ever played. Dillinger smokes cigarettes and encourages Twisp to crash cars, but he’s still a guy who "speaks with that deadpan clipped irony — in other words, exactly what we’ve come to expect from Cera" (EW.com).

Which leads me to my theory: Aviators change a personality/face. One accessory, and you are a totally different person.
