From a scene in the most kickass movie ever. Zoolander. Derek recovers brilliantly from a shut down by Hansel, calling him "han solo" and making masturbation movements. You know, the scene with Winona Ryder.
Derek: Hey I got a whacky idea. What say we settle this on the runway... Han, Solo.
Hansel: Are you challengin me to a walk off? BOO-lander.
Billy Zane: Don't do this Derek.
Hansel: Listen to your friend Billy Zane. He's a cool dude. He's trying to help you out.
Derek: Oh yeah, that's a walk off challenge my friend.
