Isn't there a limerick that commences: "There was an Old Man of Chad"

Thought everyone knew it:

The once was an Old Man of Chad
Who drove creationist quite mad
With the slope of his spine
He made them all whine
"Despite all our learning, we've been had"

[SlowBoat407]

There once was an old man of Chad
Whose stance was exceedingly bad
His knuckles would drag
And his backbone would sag
But oh, the fun dates that he had!
