Hammer and Nail

Well going out in Prague is certainly more interesting when you've got a few locals to show you the ropes. Plus it also helps when you don't have that much to do the next day, it makes drinking a few liters of beer on a school night seem a lot less... bad.
Nail Bar in Prague (I have no idea of it's real name) is a little bar in Praha 2 with a game that would certainly be banned within seconds in any Australian pub, club, bar, bistro, or even backyard. Pictured is the lovely Dita posing with the hammer and one of the large gauge nails used in the game, along with the giant chunk of tree stump. This bad boy is filled with nails that have already been hammered in and it's surface is covered with chunks of sawdust from all the miss-hits of nails from previous games.
You start by nailing in one of these large nails for each player, using the back of the hammer as a measure to make sure they all start off at the same height, and then each person gets one swing of the hammer to try and drive their nail into the tree trunk. You only get one swing regardless of whether you hit or miss and then pass the hammer on to the next person. The trouble is you're using a hammer with a chisel head on the back and you have to use this narrow part to smash in your nail, which also gets a lot more difficult after a few beers surprisingly.
Add to this that the loser has to buy shots (or beers if no one wants shots) for everyone and you have one mean drinking game.
Pictured below is my souvenir woodchip that I knocked off the tree in my first game.
