Anthony’s Law of the Workshop:
Any tool when dropped will roll to the least accessible corner of the workshop.
First Corollary to Anthony’s Law of the Workshop:
On its way to the corner the dropped tool will always first strike your toes.
Second Corollary to Anthony’s Law of the Workshop:
The accessibility of the dropped part varies directly with its size and inversely with its importance to completing the task at hand.
Anything dropped in the bathroom falls in the toilet.
