Answer:
My friend here swears that he's Irish. I have doubts, and I don't really care. She insits, though, if that's any help.
He's obviously Irish. I've heard him use/fake an Irish accent, and it was perfect. But that isn't really proof of anything. Anyone can do an accent. But I can see in on his face, and his hair is a dead giveaway. But this is only a guess based on my experience of him.
