Does the Mission Have a Motto?

Readers over at SFist recently voted on what they feel should be the motto of San Francisco, and the winner by plurality was “Not Smug.  Just Better,” with “Back Door! BACK DOOR! Step Down! STEP DOWN!” coming in a close second.  This got me wondering, does the Mission have a motto?  Does it even need one?  If so, what would it be?

What do you think, guys?  How does “PBR and Jameson” sound?
