These men are boys who grew up to become competitive shin-kickers.
Yes, that's right. Shin-kicking is an actual sport in one English town, and it looks just about as unpleasant as the name implies.
Here's how shin-kicking works. Two contestants fill their pant legs with straw for padding. They lock in by gripping one another by the shoulders. Then they start kicking. Whoever wimps out or falls down first loses.
Well OK then! The annual shin-kicking championships are held in Dover's Hill, England, at something called the Cotswold Olimpicks, which just recently celebrated their 401st year of fun. A 24-year-old chap named Zak Warren took home the crown for his second consecutive year.
The short YouTube video embedded above, shot at this year's competition, takes a look at shin-kicking in all its glory. Check it out for yourself, then let us know if you'd give it a shot in the comments.
