That was predictable. For reasons I cannot comprehend, someone thought that a human hamster wheel would be a good addition to this community play place. Sure, it could be a low-budget, electricity-free alternative to a treadmill, but there’s a reason that we only give these things to hamsters — when they fly off them it’s hilarious, whereas when we fly off them, we die.

Well, we might not always die, but we can get a pretty bad boink on the head, as this guy shows.
