I own this shirt! Only mine is green.

I bought the green version of this shirt some time ago. One of only two pony-related t-shirts I own, and the only one I wear on a regular basis.
 
May the people of Éire’s spirit, blessed by God, be in all of us. Greetings from a Scots-Irish (father’s side) hillbilly in Kentucky (Don’t ask me what the percentages are, I can’t trace my father’s family tree to farther than 1845. I haven’t finished the calculations on my mother’s side, but I’ve worked out that I’m 19.6% Cherokee thanks to my maternal great-great grandmother and my paternal grandmother and at least 2% as a descendant Dutch fur trader who came to Jamestown Va. in 1609-1612 (not quite sure which) it’s rather confusing.)

In my case, Yes, Being part Irish on my Mother’s side of the family.

Well, she’s green.  
And has a - uh, not exactly a harp but well - on her flank.

Irish-ish?

OK!
