There's a famous book written by one of the scientists at Los Alamos who claimed that the safes supplied by the government to hold top secret documents overnight when the nuclear scientists went home came from the factory set with combination 0-0-0. For fun he used to go around after hours swapping secret documents from one office to the other as a practical joke because no one ever changed the settings. He got a reputation as a master safecracker and he never told anyone his secret until he retired and told his story. This was back when the formula for the A bomb and H bomb were the most closely guarded secrets on the planet. He joked in his book that he stole the most valuable property in the history of safecracking when he messed around with America's nuclear secrets.

I forgot who it was, but I'll see if I can look him up.
