I've been in splits since the time I chanced on this. Here's a sampling.

Rand, Ayn: Hollywood screenwriter, later writer of huge thick novels, then a philosopher, but for some reason I can never find her in the philosophy reference books I look in. Maybe I have the spelling wrong.

Better still;
Darwin, Charles: Primarily an economist, who happened upon the theory of evolution after dabbling on the stock exchange. 'Darwin's whole theory of evolution by natural selection bears an uncanny resemblance to the political economic theory of early capitalism...Darwin had some knowledge of the economic survival of the fittest because he earned his living from investment in shares he followed daily in the newspapers. What Darwin did was take early-nineteenth century political economy and expand it to include all of natural economy.' [Richard Lewontin, Biology as Ideology]

Or this for that matter;
Aristotle: A famous thief. Stole all his ideas from the library at Alexandria, built after his death, which just goes to show how sneaky he was.
