A frog he would a wooing go
"Hey Ho" says Roly
Whether his mother would let him or no
With a roly poly gammon and spinach, "Hey Ho" says Anthony Roly.

Let's face it, it doesn't really make much sense.

One my daughter used to like when she was a child we got from a book of nursery rhymes

Huggity puggity puddle and fogs
The cats are to marry the poodle dogs.
Cats in blue jackets,
Dogs in red hats.
What will become of the the mice and rats?
