Now I've seen some failed wedding proposals, but I don't think I have someone's body literally fail. I don't know this guy's name, but I feel bad for him. He wanted to propose after competing in the Iron Man Triathlon. Which, by the way, way to make all of us other people look bad. That is incredibly impressive just to compete in that race, but to get down on one knee and ask a person to spend the rest of their life with you is the cherry on top.
However, it is safe to say that the proposal probably did not go as planned.
