    Well, you can't. As for you, my fine

    friend -- you're a victim of disorganized

    thinking. You are under the unfortunate

    delusion that simply because you run away

    from danger, you have no courage. You're

    confusing courage with wisdom. Back where

    I come from, we have men who are called

    heroes. Once a year, they take their

    fortitude out of mothballs and parade it

    down the main street of the city. And they

    have no more courage than you have. But!

    They have one thing that you haven't got!

    A medal! Therefore -- for meritorious....

    conduct, extraordinary valor, conspicuous

    bravery against wicked witches, I award you

    the Triple Cross.
