When Peter was a baby
He didn’t learn to crawl
In fact he never wanted
To move around at all
Until one day he had a thought
“Wouldn’t it be fun
If I could get up off the floor
Move my legs and run”
And so when he was 2 years old
He got onto his feet
Stretched his legs, kicked his toes
And ran off down the street
First he ran to nursery
Then he ran to school
He ran to university
His life was never dull
The County picked him for their team
Winning every race
Nobody could ever beat
Peter’s speedy pace
