I have to say "...wtf." Did anyone catch the men's 1500m race with Lopez Lamong and one of the Kenyans in it? The Kenyan's legs made up approximately 95% of his body. He was in last the majority of the time, but then kicked it in down the stretch, hardly making his legs work any harder, and effortlessly won the race.
But seriously, the length of his legs were scary. If you didn't see this, try youtube.
