Not mine but still a worthy yarn...
An old mate of mine used to be a labourer type for a developer (buildings not software). As he was the new boy, he was ripe for the taking.

First fix of plumbing had been done in one house and the easiest way to establish which is hot and which is cold at a particular point was to get someone to blow down the hot pipe at the boiler end. Wherever the rush of air came out was the hot tap...(you can guess where this is going).

"Oi new boy! Can you blow down the hot pipe for us please?"

Sure enough, new boy thinks nothing of it and blows down the copper pipe. Couldn't work out why everyone else was rolling around the floor laughing.

Turns out, the biggest, fatest bastard on site had dropped his pants and liberally wiped his arse around the hot pipe that new boy had so obediently blown through.

From then on, new boy carried a small length of copper pipe in his pocket...:O)

I
was sent for a "carb dryer" on site aeons ago. A small, hand held , battery operated hairdryer to dry out the wet carb of a water pump.
