A photo has been circulating of Robert Forstemann, who's a cyclist competing for Germany in the Olympics.  It shows him in his underwear, from the waist down . . . and he just might have the WORLD'S BIGGEST THIGHS.

I have no idea how he manages to sit on a bike.  Or walk.  His thighs look like the thighs on someone who weighs 700 pounds . . . only his are all quad muscle.
