After a big conference of beer producers the presidents of all the beer companies decide to have a drink in the bar. The president of 'Budweiser' orders a Bud, the president of 'Miller' orders a Miller Lite, Adolph Coors orders a Coors, and the list goes on. Then the waitress asks Arthur Guinness what he wants to drink, and much to everybody's amazement, Mr. Guinness orders a Coke! "Why don't you order a Guinness?" the others ask. "Naah, if you guys aren't having a beer, then neither will I."
