How'd They Do That?

David Maas and his wife, Dania Kaseeva, are the masterminds behind Quick Change, a speedy costume-switching act that leaves Oprah asking, "How did you do that?" "I could tell you, but then we'd have to make you disappear," David jokes.

During the act, they change costumes several times—and even switch Dania's hair color—behind fluttering, brightly colored cloths and falling confetti. Dania says men always tell her, "I wish my wife changed like you."

Dania got her start in show business in the Moscow Circus in Russia, and David's family has an entertainment background as well. The pair has been doing their quick-change act for 10 years, performing for such illustrious audiences as the Queen of England. To keep their patented quick-costume-changing techniques top secret, David says they don't let the costumes out of their sight! "We worked on it a long time," he says.
