Limerick from the Source

Some times people are lucky enough to have a boss that treats you by way of The Golden Rule.
That man, who still works where I did once, it as thoughtful as ever.
Knowing my tendency toward enjoying the crude things, he was on a visit in Ireland and thought this might be for me. About as dirty as his conscience allows....

Mail arrived with this on a piece of faux parchment, and a coin from Limerick.

And on the reverse side

I've been carrying the coin around with me, wasn't sure how to share, this is the best I can do.
