Carbomb

Pour Bailey's, Kahlua and Jamesons' in order in a shot glass (Bailey's at the bottom). Drop or slide the shot into a half pint of Guinness Stout. The shot, if dropped in carefully, looks like a Guinness inside a Guinness. The Carbomb is to be consumed in one long swallow. Mind your teeth as the shot slides forward. The incredible taste is worth the risk.
