The Blarney Stone Poem by Ima Ryma

Irish call me 'The Blarney Stone.'
A block of limestone I do be
In Blarney Castle, and I'm known
For giving skill at flattery,
For those who climb a tower high,
And give to me a heartfelt kiss,
No matter whether gal or guy,
I am for all gender on this.
Now how began this kissing thing,
Which happened a long time ago,
Has many tales in the telling.
No tale's told by me, but I know.

Millions kiss me through centuries,
I'm immune to human disease.
