1. Don't throw scribers around carelessly: Aim before you throw.
2. Never run in the workshop. Don't walk either: stand around and do nothing.
3. When using a hacksaw, break a few blades. Someone has got to keep up the manufacturers in business.
4. Never spill paint or oil on the floor accidentally: do it purposefully.
5. When using soap, make sure you spill some on the floor: it also occasionally needs a wash.
6. When using electrical appliances, stand in water so that you can see how well the appliance is earthed.
[A Joubert, st. 7C 1974]
