Trick or Treat

I survived 300+ kids jacked up on sugar and applied 300+ temporary tattoos for Trick or Treat night on Penn Avenue. Here's my own tattoo for the evening emblazoned across my knuckles; TRICK, OR, TREAT and a little black bat. I thought it might make me look tough but alas....

I'm all about commitment-free tattoos (like this love tattoo in the XXOO Bento Box) just because I like to keep my options open. So I'm wondering, if you have something more permanent, how did you make your choice?
