He's an Irish snowman, natch. There's actually quite a lot of Irishness in that picture. I'm not sure how much Irish blood my niece and nephew have in them but they are at least half Irish and my Baby Girl is also half Irish. So among the three kids at least 1.5 of them is Irish. There's an interesting fact for you.
Also, by "Irish", I do mean "American whose ancestors hailed from the Emerald Isle". I'm not sure any of them know what or where Ireland is. Though their grandfather is an Irish citizen who has been to Ireland exactly once. Who knew that was even possible?
And on that topic, if someone says "top of the morning to you" on March 17, please respond "and the rest of the day to yourself". Drives me crazy that no one ever responds appropriately.
