Question: Company A has 25% market share and 75% profit share. Company Z has 75% market share and 25% profit share. Which company is doing better?

Answer: If you said anything other than company A, then you are dumber than a doorknob.

A fairly comprehensive look at and tear-down of the “market share = winning” philosophy. This should put an end to it but it won’t, obviously. All kinds of humorless sorts do not get this joke for some reason.
