Lindsey Vonn is one of the most famous skiers in the world, but when she goes undercover, not many people can recognize her.
The word "undercover" is being used loosely, of course.
Vonn posed as a ski ticket agent in Vail, Colo., and she was able to fool many customers even after she told some of them her first name.
The best part of the video has to be when one man recognizes her and totally creeps her out. Hopefully he was just messing with her when he said he had a giant poster of her on his wall and even dreams about her.
