People around the Bay area in California will be familiar with the annual "Bay to Breakers" run. For those who aren't, it is more of a social event than an actual race. Some people run it seriously, most people walk or jog it, and people do it in costumes ranging from truly elaborate to completely nude.

I wish I could take credit for this photograph, which apparently has been floating around on the internet for some years now, and perhaps some of you have seen it before. For those who haven't... be warned, this picture is mildly NSFW. I resized it large enough that it wouldn't display automatically with this post, you'll have to click on the attachment.
