Way back in 1988, Wes Cherry was a Microsoft intern and during his time at the company he created the biggest time waster the world has ever known: The Solitaire computer game. Cherry built the game out of boredom instead of being directed by his superiors. But he bosses -- including CEO and founder Bill Gates -- liked the game so much they added it to Windows in 1990. Since then, Cherry has made exactly zero dollars on his creation. And you thought your internship was bad.
