Did You Know...
...that after Parker Brothers executives turned down the game of Monopoly because it had "52 fundamental errors" (including taking too long to play), a copy of the game wound up in the home of the company president who stayed up until 1 a.m. to finish playing it? He was so impressed by the game that the next day he wrote to inventor Charles Darrow and offered to buy it!
