"DID THAT HURT?" he yells.
        "No, Sir!" came the reply.
        "Why not?"
        "Because I'm a U.S. Marine, Sir!"
        The captain is impressed, and walks on to the next man.  He takes the
stick and whacks the soldier right across the rear.
        "Did THAT hurt?"
        "No, Sir!"
        "Why not?"
        "Because I'm a U.S. Marine, Sir!"
        Still extremely impressed, the captain walks to the third guy, and sees he

has an enormous erection. Naturally, he gave his target a huge WHACK with the swagger stick.

        "Did THAT hurt?"
        "No, Sir!"
        "Why not?"
        "Because it belongs to the guy behind me, Sir!"
