Just remembered this... unfortunately the best stories I have just don't involve me. Ever.
My mates dad was an electrician, he was self employed and enjoyed a fair degree of success. He had just taken on an apprentice and was showing him the ropes. The property that they were in on this occassion was to install the wiring in a complete shell of a property that was being redeveloped. The only thing that had been completed thus far was the basic plumbing and the installation of a toilet. A number of raw materials were stacked up ready for use in the centre of all the rooms, sheets of plasterboard and bags of plaster, lengths of pipe, reels of cable (you get the general idea.)

The apprentice went for a shit while the boss was up in the loft sorting out the cabling. The apprentice called out to the gaffer. Unfortunately their wasn't any toilet paper and he wanted to wipe.

The opportunity for mischief was too great by far. went over to the rolls of loft insulation that were stacked up beside him, grabbed a handful and handed it to his protege, suggesting that it should clean it off.

Apparently he saw the funny side after a few weeks.
