The alltime best Halloween costume I'm aware of is when Chris Lear dressed up as a testical. Yes, a testicle. He called me today to remind me of that.
I'll try to track down a photo. He wore a sheet, painted it pink had some dark markings. Classic.
Several years ago, we had teams submit their costumes for a contest.
I'm on a train on my way to NYC with crappy Internet access so someone else google it and find the link.
I know in the past some of you have had some clever ideas - like this couple that actually dressed up as LetsRun.com:
So share away.
PS. Stay classy. Please don't post anything that would make my wife blush.
