Calvin: Dad, will you explain the theory of relativity to me? I don't understand why time goes slower at greater speed.
Dad: It's because you keep changing time zones. See, if you fly to California, you gain three hours on a five-hour flight, right? So if you go at the speed of light, you gain MORE time, because it doesn't take as long to get there. Of course, the theory of relativity only works if you're going west.
