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."
