I'm not sure who came up with this game, but at most of our stops on our European drinking tour we'd have extended periods of time waiting to head to the next stop. Someone in the group came up with this little coaster challenge. The game is to take a stack of ten coasters, put them at the edge of the table, and then hit them up in the air and catch them all with one hand. After we got it down with our right hand, we started doing our left, and then alternating hands. A couple guys even started doing two hands at once. I'm not that good yet.
