I just can't resist... from another forum:
Amsterdam was hosting a conference of beer producers. At the end of the day, the presidents of all beer companies retired to the bar for a drink.

As the waiter approaches, the president of Budweiser calls out, "I'all have the best beer in the world. Give me 'The King Of Beers', a Budweiser."

Adolph Coors says, "Bring me a Coors, the only beer made with Rocky Mountain spring water."

"I'll have a Miller Genuine Draft," says the president of Miller.

Arthur Guinness down and says, "Give me a Coke, please." The other brewery presidents look over at him in amazement. "Why aren't you drinking a Guinness?" "I'd love to," says Mr. Guinness, "but I figured if you guys aren't drinking beer, neither would I."
