There's a big conference of beer producers in the most beautiful town
in the world: Amsterdam, the Netherlands...
     
At the end of the day, all of 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."
