I had to share this one...

During a major International Beer Brewers Conference, a few of the
attendees decided to step out for a few beers.
Once at the local pub, the rep for Budweiser orders a Bud.
The rep for Miller orders a Miller.
The rep for Coors orders a Coors
The rep for Heineken orders a Coke.
When asked why he ordered a Coke, he replied:
"well, you guys weren't going to be drinking beer, so I decided I
wouldn't either.
