20 questions

While driving in the car, we play a game called '20 questions'. One player thinks of something, and the others have 20 yes/no questions to guess what it is (20 bits of information is over 1 million separate entities). Typically, the first two questions asked are 'Is it alive or dead?' and, if the answer is 'Dead', the next question was 'Was it once alive?'
