I think that for Spooky Day (or Halloween, All Hallow’s Eve, Samhain or Samhuinn, Nos Galan Gaeaf, Allantide as it may be where you are), it would be very excellent if everyone would be Edward Snowden.
I’m not saying he would necessarily have an easier time travelling if he were to look just like everyone else, but it probably wouldn’t hurt.
I am attaching a picture of Mr. Snowden to this post. However, your likeness doesn’t need to be perfect — apparently Bolivian President Evo Morales was considered to have a pretty good resemblance, by the people who caused his plane to be intercepted. (Oh, the mistakes we could all avoid if people would just bother to learn a little Spanish.)
Honestly, I think the two look pretty different. Make sure the costume shop gives you the right mask.
