‘Human Elevator’ Smoothly Jump-Climbs Up And Down Two Walls

This is a video of parkour athlete Nico Fischer demonstrating his skills by repeatedly (and smoothly) jump-climbing up and down two parallel walls without touching the ground. His friend Aziz gave him the nickname ‘Elevator-Man’, which I’m adding to my list of blackballed houseguests. I made the mistake of letting another parkour friend come over once and he tore off my shower curtain rod and broke my hamper. You said you just had to pee, bro!
