Full disclosure: I "borrowed" this joke from John Cleese's early TV special, "How To Irritate People." It was airplane pilots in that one, but it works just as well with these guys.

This was one of those cases where I came up with the joke before I had the stills from the movie to go with it. Seems obvious in retrospect that these frames fit the bill, but it was actually tough to try to locate a scene that would work.
