From the Gazette van Detroit:
The CEOs of three large breweries meet at a convention and decide to go for a drink together.
When the waiter arrives to take their order, the Heineken boss naturally orders a Heineken beer, the Budweiser boss orders a Bud, and the boss of Stella Artois orders... a Coca Cola.
To the astonished looks of his colleagues the man says, "Well, seeing as neither of you is having beer, I had no other choice but to keep you company."
