Well, since I'm an Irish-Italian born in the U.S., I will give you three answers for the price of one. Take NONE OF THEM seriously.
America! - America is fat and lazy with a bloodlust a mile long and a short attention span. Also, according to the best terrorists, we're the most evil fucks ever to stand up and say "Yo!".
Ireland! - Gimme a pint and I'll crap potatoes and bomb a restaurant. Also, SHEEEEEP!!
Italy! - Pasta pasta pasta pasta pasta! And I can't talk without moving my hands around with a number of funny gestures.
