Actors are also notoriously superstitious. They religiously refer to a particular Shakespeare production as “the Scottish play” and forbid whistling in dressing rooms.
Baseball players are also well known for a variety of superstitions: no one talks to a pitcher throwing a potential no-hitter, even changing their walk-up music to break out of a slump.
CIA operatives are also superstitious. Before leaving on a mission, agents stop by the statue of America's first spy Nathan Hale. They leave either 76 cents (the year Hale was executed) or a quarter (in honor of the man depicted on the quarter, General George Washington, under whom Hale served.)
The money is donated to the CIA Officers Memorial Foundation.
