Whenever I hear that Rolling Stones song about how “wild, wild horses couldn’t drag me away,” I get really skeptical. Um, have you ever seen a wild horse? Wild horses drag things away—that’s what they were born for. Wild horses could drag away a school bus with its emergency break engaged and other, smaller wild horses pulling in the opposite direction. I know this song is metaphorical, but it’s still a preposterous declaration—especially when you consider that it’s being sung by Mick Jagger, who a domesticated goat could probably drag away. The only thing a wild horse can’t drag away is another wild horse of equal size. If you rigged up some rope between two wild horses and they took off in opposite directions, they would rip each other in half.
