So, how about a new poll- how many screwdrivers does the average
airplane owner own?

All of the screwdrivers one owns can be classified into M sets of head
types and sizes (1/4" slotted, #2 Phillips, etc.) All of the screws
that need turning on all of the aircraft, cars, buildings, power
equipment, etc that one owns can be classified into N sets of head
types and sizes.

It is an immutable law of the Universe that M = N - 1.

The only known way around this is to have a very small set of
screwdrivers and a large budget for replacement screws:

With a Dremel tool and a cut-off wheel, _everything_ takes a flat-blade
screwdriver.
