A damn good cartoonist
who chronicled the Cartoon History of the Universe
, volumes one and two, perhaps more.
He didn't write the Cartoon Guide to Economics, better than any mere textbook I've ever seen when it comes to sheer usable economics knowledge (And it mentions Thorstein Veblen).
His Cartoon Guide to SEX isn't smutty but is quite interesting and informative, an abridged version of which (at least the historical/evolutionary development portion) appeared first in his History of the Universe, volume one.
