Pub rugby? Each bar has a different drink (e.g. 1st pub has a pint of larger, 2nd pub has a pint of guiness and so on). If you manage to down your drink in one, you get 5 points put on the scoresheet, then for an extra 2 points you can do a shot of something (decide whether its alternating shots for each pub or just the same one throughout the night beforehand). I think that you only get a chance at the extra 2 points if you have downed your drink in 1. I think you still get points if you don't down your drink in 1, so if you stop once you get 4 points, twice twice you get 3 points etc (I think that last rule applies, I can't remember a lot from the night we did it). Also obviously, International drinking rules apply
If someone tries a down in one and either chokes or pukes, does the opponent get awarded a penalty try?
