That doesn't surprise me, given the quality of Asimov's work.
Not sure what you mean there, Homer. A lot of his fiction was pedestrian, but the
Foundation series hugely influenced subsequent science fiction. And his non-fiction writing was a model of clarity and insight.
Speaking of dirty limericks, Playboy ran a page of them by Shel Silverstein (I think) back in 1968 or 1969.
I still remember two of them:
There was an old man from 'Stamboul
who soliloquized thus to his tool
"I gave you my health
My youth and my wealth
And now you won't pee, you old fool!"
And there was another one that requires some explaining. First, it referenced a certain racist Alabama politician. Second, the illustration showed Ku Klux Klansmen lining up to vote; protruding from under their robes, there could be seen something strange:
A lonely old farmer named Hollis
Took possums and snakes for his solace
His children had scales
And prehensile tails
And voted for Governor Wallace
