Tom Clancy was the butt of many a joke in writing circles. There are Tom Clancy mad libs plot generators, for instance:
The [USSR/Arab/Chinese] government is funding [terrorists/IRA/neo-Nazis] to create a [nuke/dirty bomb/chemical weapon] to destroy the [national landmark/military asset/major city] and it's up to [Hero Name], a tall, white, (ex?) [military/spec-ops/CIA] specialist to destroy the threat via the use of overwhelming military hardware.
He hasn't written anything in fifteen years, but was putting out up to a dozen novels a year. This is because he uses ghost writers; aspiring novelists get picked up by the publisher and paired with Clancy, he'd help them figure out a plot, then let them write it while he played golf, and gave advice on military hardware and story aspects from time to time. Then the novel comes out with "TOM CLANCY" in huge letters, and the aspiring author's name in small print below it, or not even on the cover. The aspiring author gets a smaller cut than Clancy, but still makes more money than he would selling under his own name.
Clancy was a decent author, but if you've read anything of his that's come out since ~1998-2000, it probably wasn't really written by him.
