Either a gaffe by the writers/directors, or a deliberate funny sequence
I'm right now watching "Hiroshima, Mon Frere," and Ben Stein clearly says to the class for when they are presenting their science projects, "Miss Clark, Mr. Odeno, are you prepared?" But it's two girls that get up...no "Mr." I found this funny, but I'm guessing that this is so subtle that it was probably missed by most at the time! Or, maybe Ben Stein messed up the line but they didn't care!
When I read about the evils of drinking, I gave up reading!
