So far, on the faerie front, I've got "Powered by pixie dust" and "Flap if you believe in faeries" (thanks, wolfdancer). I'm planning on adding a bunch of Labyrinth quotes, and anything I can find about the wonderfulness of imagination. Any other suggestions?
I'm bringing "Deadly ninja throwing button" and "Harmless ninja throwing button" out of back stock, and possibly "Middle-aged mutant ninja mother". I've got NINJA on black, with the letters just half-outlined in white.
For the pirates, I've got "Why are pirate jokes funny? They just ARRRRR" and "We prefer to be called Buccaneer-Americans".
