Speaking of movies, Slate.com recently had a piece in which they declared John McClane's "Yippee Ki Yay, Motherfucker" one of the best action-movie lines of all time.
They list a few others, and I was sad to see they didn't include my favorite line — and I think I can vouch for my brothers on this one. It comes in Arnold Schwarzenegger's "Commando." Right after Arnold's John Matrix character fights a villain in a motel — forcing him to burst into other rooms with scantily clad ladies — the villain corners Arnold with a gun. The villain then says, "Fuck you, asshole." The gun goes CLICK. Then Arnold responds, "Fuck *YOU*, asshole." Anyway, it's awesome. Maybe you have to watch it to appreciate it.
