Earlier this month, Slate ran a review of Live Free or Die Hard (which dammit, I still haven't seen yet), and contained therein was a link to another fun article about action movie one liners. The greatest, of course, being "yippee ki yay, motherfucker."
In the review, the author suggested a contest in which readers could submit fake action movie one liners. Here is a link to the results, which I found amusing. Among the ones that made me giggle out loud over my morning java:
"Welcome to America -- douchebag."
"My karate will disintegrate your genitals."
"Less talk, more dying."
"Your ass is about to get its own ass handed to it."
