An oldie, but still a goodie...

After work, all the brew masters from the Munich breweries sit together in a pub. Needless to say, each brewer orders beer from his own brand, i.e. the Löwenbräu guy orders Löwenbräu, the Hacker-Pschorr guy orders Hacker-Pschorr, and so on. Last one to go is the Augustiner guy. He orders a Coke. Everybody is stunned, asking - "Why?" - "Well", he finally says with a wide grin, "if you are not ordering any beers, then I won't either."
