That's actually an excerpt from some Buddhist Nursery Rhymes I wrote on a thread on e-Sangha. Here are some more:
"Don't get mad," the Buddha said
"It sets a fire inside your head."
"I hate this! I'm mad at that!
"I'll whip the dog and kick the cat!"
Like taking poison, hoping someone else will die,
Anger makes us weep and cry.
It's never good, always ill,
And through kamma we pay the bill.
That dog, that cat, the hated OTHER
Was, in bygone times, your mother.
Above all else, be kind
Let love, not anger, rule the mind.
Jack and Jill
Went up the Hill
To listen to some Dhamma.
Jill came back
As a boy named Zach
And Jack came back as his mama.
There was an old man
Who lived in a shoe
He studied Lord Buddha
Confucius and Lao Tsu.
He saw it was fruitless
To chase after riches
He learned how to live
Life free without glitches.
Most people said "He's just an old fool,"
But personally, I thought he was cool.
That man was me, in a former existence
So now today, I meditate with persistence.
It's raining, it's pouring --
Isn't Samsara boring?
Impermanent, inconstant and stressful
Seldom blissful, at peace or restful.
So spend much time on the mat, dear friend
And you'll reach Nibbanna in the end.
May we find, as others found
The perfect Mind like fire unbound.
I had too much coffee that day.
