It's fake. I saw another version of the video with the same two guys. In the other version the guy on the right had grey glove instead of yellow and you heard them yelling no four times instead of only twice.....
No way two guys could roll a spool of wire that large up a flight of stairs.
It is entertaining as hell though....

Car alarm starts going off before the spool actually hits the car....
That was my thought as well. I don't think the spool ever actually hit the car did it?
I know it's fake, but what part of it is??
