I had some friends that participated in this beers around the world contest. The way it worked was you had a card with all the different countries. Every time you drank one from that country, you got a stamp. They said it was fun, especially working your way through the good beers, but some they said were awful, like from some of the Asian countries. If you made it through all the beers of the world(Not sure the time frame if it was a month or year or what) you got a shirt and your name was engraved on a plaque in the establishment which was considered an honor.
