Some 'new boy' type pranks can go horribly wrong - often because the pranksters lack brains: I was appalled to read of one where they stuck a tyre/tire inflator in his rectum and exploded his intestines, killing him.
Worse thing I experienced was someone nailed my overalls to floor and other painters painting the back of my shoes when up a ladder.
Anyone remember the famous Monty Python sketch 'The Piranha Brothers'? Nailing to a floor reminded me.
In a part of the Merseyside area. ( The POSH part no outside toilets or tin bath's ), but happier days none the less.
