DEFINATELY fake. he would decapitate himself near the end, the stairs arnt wet, and he has no traces of snow on his skis, and it would be very easy to just stand there on the kink, especially with 2 side by side rails. FAKE!!
Dont know if its fake but it is possible to rail that one. It is the stairway going down to the copenhagen subway and the material is not alluminium, its steel.
