Hey, it's "everybody thinks they're me day"!
Seriously, I drink Guinness, I drink Jameson, I drink Vodka (and call it Poitin, since it's basically the same thing, and I can't find and decent Poitin). Baileys and Disaronno is pretty good mixture too, but that's 1/2 Italian.
Someone pinched me cause I wasn't wearing green. I looked at her, said "I can get away with it. Irish."
While I'm only 3/8's Irish, I can put on my G-G-Ma's accent at-will. I have bright red hair too.
So when I say, "I'm Irish", with the accent, no-one argues.
