Not really just had on my wool pea coat and fedora, while walking around with friends.
Good thing it was thick wool since that bounced the eggs off from some drunks in their car, also nice that I had on my steel toe work boots for when I walked over and kicked their door and they sat inside like wusses. Not even man enough to get out and let me get my daily workout in. Course they tracked us around the block and through a police lot till we got over a ditch and slipped through some apartment alleys.
@brainwood: That's the whole point of halloween -- time to get silly. And I just proved that you're never too old to do silly and stupid things. According to this wiki article Halloween is only celebrated in a few countries, so if you don't live in one of those countries you may have never heard of it.
