Got shown this in work today and although you wouldn't want to be on the arse end of it, it is very funny.
Lol. Also known as the 3 man lift. We did this to a guy in my last work place. He was a bit of a wanger and I honestly think he died a little inside when he got tea bagged
The next time im at a building site I`ll give it a go..Don't think it will have the same effect tho...
