Just a few tools and supplies I've heard 'to be picked up by the apprentice'
- a bucket of steam
When the apprentice comes back telling you the steam keeps coming out tell him to hold the bucket upside down and walk quickly.
- spotted paint
- striped paint
- spots for the spot welder
- a glass hammer
- a left handed screwdriver
- a metric adjustable wrench
Tell the apprentice you stripped a metric bolt because you used an imperial adjustable wrench
- a long weight (wait)
You need to ring the supplier before that prank. They are usually more than happy to help out.
