When I was very young, I came home to find my dad playing on the NES. I asked him what he was doing, and he told me that the "games" on the machine were actually training programs used to keep astronauts at NASA sharp. Later in life as I started playing video games myself, I learned that this was not true, but until very recently I was convinced that the game he was playing at the time - Tetris - was an astronaut training game.
