I don't know if it is or isn't P-shopped, nor do I much care - it looked like a blowup doll to me upon first glance, but seriously, stop a second, LOOK at the building.....no, seriously, LOOK at the building, and STOP saying he's floating in the air or has nothing to stand on.
It's a friggen flagstone building, with TONS of places to get a foot/toe/dong-hold on.
Haven't you ever seen the freeclimbers who scale what looks like a sheer rock face with nothing to grab on to? That building probably looks to those guys like the equivalent of the bunny hill to skiers!
