If you want to see some ridiculous bruises, check out this contest from The Life and Times of Lucy in Da Sky With Diamonds, sponsored by Scarred Derby Designs. (Warning: I wouldn't look at these while you're eating.. also, some could be considered NSFW because some girls are showing a bit of booty.)
Check out the site to see how you can vote for the "best" bruise. The contest ends Friday, February 11th at Noon EST.
I didn't submit a bruise, because I didn't really have anything too epic. But here's a pic I found from last April. It's the front of my leg, at and just below the knee. I don't think it hurt as much as it looks like it did. Bruises are kind of a roller derby badge of honor.
