Sunlight Soap

You can use it with great pleasure and ease
Without wasting any elbow grease;
And when washing the most dirty clothes
The sweat won't be dripping off your nose
You can wash your clothes with little rubbing
And without scarcely any scrubbing;
And I tell you once again without any joke
There's no soap can surpass Sunlight Soap;
And believe me, charwomen one and all,
I remain yours truly, the Poet McGonagall.
