When I was 4, I thought there was a reason for all superstitions. I thought the reason why people didn't step on cracks was because I knew the Earth was round, and so if you tripped on the crack you'd fall off the Earth. So when I was in Disneyland, I accidentally tripped on a crack. "MOMMY, HOLD ME! I'M GONNA FALL OFF THE EARTH!" Turns out I didn't fall off the earth. Instead, I got a bruise.
