Living on Borrowed Rhyme

Puss in Boots has found his roots,
That cat knows how to sing.
Jack's stopped going up that hill,
And Jill's just doing her thing.

Humpty Dumpty invests in glue,
And now he's playing Wall Street.
Little Boy Blue plays trumpet too,
He's got you tapping your feet.

Baa baa black sheep's gone PC,
Her fleece has turned quite green.
She follows Mary all about,
And joins Puss to see the Queen.

Just what makes a weasel pop?
Or makes a ladybird fly?
Who marries owls to pussycats?
Did the three little pigs have a sty?

I've been living on borrowed rhyme,
And hope this song is heard.
To settle once upon a time,
That I am quite absurd.
