Ages ago, I used to have a book with all kinds of nasty little parodies on children's nursery rhymes, which were not quite up there with the Russian "kiddie sadist" poems, but were still pretty good.
"Mary Had a Little Lamb", in particular, seemed a popular subject.
I've finally found a couple of them online.
Mary had a little lamb
She ate it with mint sauce
And everywhere that Mary went
The lamb went too, of course.
... Or, if you prefer:
Mary had a little lamb
The doctor was surprised,
But when Old McDonald had a farm
He couldn't believe his eyes!
