Class of 2013 hand sign and slogan?

So at my school each class has a slogan and a hand sign.
For our Seniors last year (class of 2010) their slogan was “eXpect the uneXpected” and their hand sign was making an X with their arms.
I have no idea what we are going to do for our slogan but for our hand sign i was thinking of doing this

So if you could please help me come up with a slogan. And tell me what you think of the hand sign or come up with your own.
And please dont answer saying that the world is going to end before that anyways, I just want to be prepared if the world somehow doesnt end.
Thanks
