"Badges? We ain't got no badges. We don't need no badges. I don't have to show you any stinking badges!"

What is it about that line? It sticks in your head, seemingly for life. It was first uttered in a 1948 movie, Treasure of the Sierra Madre, and has been repeated countless times since then.

Indeed, a fella named Darryl has set up an entire web page devoted to the subject: Stinking Badges, which attempts to document every known reference to the line. It's shown up in a surprising number of places. Check it out. (Thanks again, Jerry.)
