One trappy apprentice who had a bit too much to say for himself; verdict: zip-tied to stanchion and copious quantities of Trefolux applied.

Welding re-bar accross the miscreant's toe caps was another one I recall.

The above escalation was triggered by said apprentice's initial reluctance to make tea as required and his childish (but inventive) original protest of drilling and screwing his spark's enamel mug to the canteen table and then filling it with tea. Cheeky little get left a straw in it and I think that's what sealed his inevitable date with the cutting paste.

When I was a factory electrician, we wrapped one guy's car with one of those big rolls of cling film that you wrap up shipping pallets with. We used the whole roll. Must be a mile of it on one of those rolls. His car was well "preserved".

For another fellow, we drilled and tapped his tool box for a Zerk fitting (grease fitting) and filled the whole tool box up with grease through the fitting. I thought it was funny at first, but the guy really went off the deep end when he found out what was done, and I honestly thought he was going to hurt someone badly.

ha ha! we hoisted one blokes motor 18feet in the air on a fork truck and left him to figure it out

Funny as..., but I'm not surprised he went nuclear, ad hominems, fair enough but my attitude is that if you dick about with a guy's tools then you do so at your own risk.
