Plenty

An Irish man, a Mexican man, and an American man are sitting on the edge of a cliff. The Irish man takes a sip of his beer, then throws it into the ravine. "Why'd you do that?" the Mexican asks. "We got plenty of those at home," the Irish man replies. The Mexican takes a bite out of his taco, then throws it into the ravine. "Why'd you do that?" the American asks. "We got plenty of those at home," the Mexican man replies. The American takes a good look at the Mexican, then pushes him into the ravine. "Why'd you do that?!" the Irish man asks. "We got plenty of those at home," the American man replies.
