My favorite one was the word "Amistad!" translated Spanish->English:

    Amistad! -> Friendship!

You could add more exclamation points, and they'd show up on the other side:

    Amistad!!! -> Friendship!!!

But when you reached five, you apparently hit some sort of context changeover, because:

    Amistad!!!!! -> Murder!

Sadly, it has since been fixed.

if someone kept on yelling "Friendship!" louder and louder, it might lead to murder...
