Last week, Lindsey Jacobellis lost what looked to be a sure gold medal in the snowboard cross final when she made a hotdog move and, in the parlance, wiped out. I just don't understand it. Lindsey had it all worked out: She would think of her Visa check-card being stolen, get all relaxed because she is covered, and swoosh to victory. That's what the coach said on all those commercials. I guess the moral of the story is don't buy a hotdog with your check-card. It isn't covered.
