I found this quote at a web site called Open Writing. It doesn't give a title or any other useful information, though:

I once knew a man and he was an encyclopaedia.
He could tell the weight of the moon to an ounce
And the name of every star.
He'd stand on a slope with a big telescope
And squint at Venus hard
Till all the pas of the girls on Mars
Complained to Scotland Yard.
For he knew all about etymology
Hebrew, Shebrew, ju-ju ology
Shin tacks, tin tacks, hob-nailed boot jacks.
He was full as a Pickfords' van.
He'd jaw for a week on ancient Greek
And speak of Plato too,
Of pots and pans and things in cans
And owls that went too-woo.
He'd analyse frogs from the Isle of Dogs
And set the Thames alight
Eat fish and chips and peas with pips
And give us all a fright.
