There's a big conference of beer
producers. At the end of the day, the presidents of all beer companies decide to have a drink in a 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?" his colleagues ask.
"Naah. If you guys won't drink beer, then neither will I."
