A 25-year-old teller at a TriBeCa Citibank finally figured out how to protect your savings from the hands of dastardly robbers. Make fun of them! On Monday evening, a potential robber walked up to her counter and said, "Excuse me Miss. This is a robbery. Give me all your large bills. Don't do anything stupid." Thinking it was a joke, she laughed in his face, and then quickly told her manager once she realized he wasn't kidding. But the embarrassment was just too much for the crook, who fled before he could get any cash. He should have dressed up as Darth Vader—nobody ever laughed at that guy.
