you cant beat the combination of gentleman's drinking rules and ring of fire.
Pub golf was another good one tho, each drink has a par (number of swigs it takes to drink) e.g pint of stella is about 3. There are 18 holes (pubs) and 18 different drinks (you have to plan it out abit first!). A complete variety of drinks is required, e.g cider,bitter,larger,shots,spirits etc. You need to write down how many swigs people take at each hole, and the person with the lowest score at the end of the night wins. If you really cant stand the drink, you can pay to change it, usually a pound, but the chosen drink must not be the same as any other drink on the list that night. The winner wins all money paid for changing drinks and ofcourse the honour! Golf attire is optional, but definately adds a few laughs!
