Great Beer Joke

The leaders of the big beer companies of the world decide to meet for a drink after the Great American Beer Festival. The president of Budweiser says, "Ah, the King of Beers!" and orders a Bud. The CEO of Miller says, "Nothing but the High Life for me!" and gets a Miller. The head of Coors says, "The Rocky Mountain spring water makes the difference!" and orders a Coors. Finally, it's Arthur Guinness's turn. He orders a Coke. "Why didn't you order a Guinness?" everyone asks. He replies, "If you guys aren't having beer, then neither will I."
