Great article detailing some of the unintentional hilarity on offer (and there was quite a bit of it):

"Japanese pole vaulter Hiroki Ogita failed to qualify for the pole vaulting final after it appeared that he dislodged the pole with, well … with his penis, folks. With his penis. Further replays appeared to show he probably knocked off the pole with another body part, but that wasn’t nearly as painful, or viral, of a story"
The japanese pole vaulter fouling out on account of his penis was my personal favourite. I am told that female pole vaulters often do the same with their breasts, especially in practice!
