Ask for an Irish Car Bomb at some bars this St. Patrick's Day and you might get turned away. The combination of Irish stout, Irish Cream liqueur and Irish whiskey (usually Guinness, Bailey's and Jameson) is considered offensive because of its name, which comes from the weapon the Irish Republican Army (IRA) regularly deployed in its battles, once exploding 22 cars in Belfast in one day. If that makes you uncomfortable, we suggest swigging Bushmill's instead.
