Video: Lindsey Vonn Goes Undercover at Ski Ticket Counter
I'm counting this as the definitive proof that the Clark-Kent-in-glasses trick works, and no one at the Daily Planet would suspect Superman is among them. Even when the people are told at the end of the video that they just bought tickets from Vonn, they don't really buy it. The psychological aspect of the Superman disguise is clearly underrated...or Olympic athletes are that anonymous.
Also, Lindsey Vonn speaks German -- who knew?
