What's the best costume you've ever worn/seen for Halloween?
Spouse and I dressed up as nerds for a couple years and had the greatest time walking around being the ugliest, nerdiest guys. When we lived in LA, we'd stroll Santa Monica blvd (a Southern California tradition) on Halloween night with a hundred thousand other revelers. Each time we'd see other "nerds" we'd run up and geek out with them. Good times.
