Meet Flikr user CS87 (aka Insane Splits Guy). We may never know his real name, but his flexibility is something we won't soon forget. I particularly heart this photo of him doing this side leg split -- in jean shorts no less. How does he do it? I haven't been able to do the splits since, well, actually ... I could never do the splits. You can see more of CS87 showing off his incredible talent on his photo stream. Check out his splits in the snow if you have a chance. That's my other favorite. I've rounded up some more insanely flexible dudes for your viewing pleasure. Take that, Kyle Richards!
