I once was involved in a "beers around the trailer park" party. This is based on the "beers around the world", where each guest brings a 6 or 12 pack of beer from different countries, but for this we each had to bring cheap beer. We had beers such as Fat Cat, Pearl, Olympia, and a bunch of other very cheap beer. The winner was the first one to drink one of each beers or pass out drunk first.
Fun was had by all.
