Ask any film geek, they'll tell you. The geek crew hates this scene because they loved it enough to memorize it, so now it's pass . Long after folks are through thinking Tarantino is cool, this scene will remain as a testament to scribbler mindfucking in Screenwriting 101. Walken wants information. There's no point in lying.
Hopper smokes a cigarette and thinks about it.
If he gives up any information, Walken and his gang of cutthroat killers will track down his son and skin him alive. Better to save Clarence by telling a story so offensive there's no way Walken could possibly let him live. It's a dance between bad, bad men. Fan-boys are an annoying lot. The most that can be done is to attempt painting that butterfly excitement gut reaction in lurid prose.
