The only guys that parkour are guys like Schmidt from The New Girl — at least, that’s what I imagine them to be.

This cat, maybe we’ll call it spider-cat, literally walks down the side of a fridge. It’s the coming of Cat-sus. All praise cat!
The little meowing the cat does before it starts is their way of shouting, “Parkour!”
