There once was a mouse
Who lived in our house
That ate all the cheese and custard
That was until we found Busted

He was a cat that had done the rounds
With at least one hundred hounds
His tail was quite bent
His ears they were lent

He was quite slim
When we found him
Though around the town
He was no clown

He very soon earnt his keep
Catching that mouse while we were asleep
Watching him play with his catch
We knew there would never be a match.
