Parkour

If you've never heard of parkour, it's basically when someone jumps and swings and flips on things like brick walls, cement steps and metal railings. Crazy, right? And people only use their superhuman skills to pull off these stunts; no equipment is allowed.

We would all be so boned if zombies could actually do this stuff. Or, you know, if they actually existed at all. But especially if they existed AND had mad parkour skills.
