I go the gym and I try to run on the treadmill and I listen to music but it doesn't motivate me enough. So I'm going to get a recording of a pack of wolves gaining on me. People would be like, 'Why is that guy crying on that treadmill over there?' 'I don't know, but he's been yelling, 'help' for like 20 minutes. He's getting a good workout.
