I think whomever said, 'curosity killed the cat' should be number one on the list of geniuses. I'm not a big J. K. Rowling fan and just went to look at her style.
I see that she has a $1,000 prize in a poetry contest at:
http://www.poetrycontest.com/j-k-rowling/
I am not promoting this, know nothing about it, have never entered one but do know that there have been many scam sites to pay money to enter, etc. I'm just pointing this out to whomever might be interested and wants to check it out.
"Grigotts Wizarding Bank poem:
by J. K. Rowling
Enter, stranger, but take heed
Of what awaits the sin of greed,
For those who take, but do not earn,
Must pay most dearly in their turn,
So if you seek beneath our floors
A treasure that was never yours,
Thief, you have been warned, beware
Of finding more than treasure there."
