"I have never..."
I Have Never is what those of us who don't want to know what "nevering" is call I Never. It is a simple drinking game, best played about halfway through an evening, preferably at the point where everyone has had a few pints and is feeling rather good about the world. It can be played with pretty much any group of legal drinking age, though it is probably wise that parents and other easily-shocked acquaintances are not present. As shall become apparent, the better the other players know you, the more drunk you will become. Many university societies use the game an ice-breaker, usually in conjunction with other house rules.
The Setup
Everyone should have an alcoholic drink in front of them. This should preferably be of a reasonably low percentage and reasonably voluminous unless you are playing with Russians, Poles, Irish, Scots, Rugby Players, Women's Hockey teams, Medical Students, or Vikings. A pint of beer is perfect.
Generally, it is best to decide on a chairman of the game. The chairman's role is to resolve any disputes and to hand out penalties for any broken rules. It is also the chairman's duty to remember who's turn it is.
Everyone should sit around a table with their drinks in front of them and, once people are ready and the rules have been explained, the chairman should begin the game.
Play
The basic rules of I Have Never are very simple. The person who's turn it is calls out to the table "I have never..." followed by something that they have never done. Anyone who cannot honestly say that they have also never done whatever it was must drink a forfeit, usually one or two fingers of their drink.1 Play proceeds to the left.
Depending on the group, there may or may not be penalties for dishonesty. For instance, if "I have never had sex on the beach" is called and Simon doesn't drink, but Joanne knows that he has, she may chose to inform the chairman, and the chairman may insist that Simon down half his pint. It can even be mandatory to challenge dishonesty and inconsistency may be harshly punished. This latter rule has lead to the UWA Paintball Society traditionally opening with "I have never slept with Sarah" and the following players calling "I have never slept with" then naming one of the people who drank in the first question, thus forcing Sarah to drink rather a lot...
Naturally, as with other truth-telling games, if it is not played light-heartedly, there is a high risk of humiliation. For this reason it is often a good idea to set a limit on the number of rounds that will be played. With a large group of people, twice around the table can be a sensible number since it allows people to exact revenge on those who have embarrassed them without descending into potentially scandalous one-upmanship. It is also possible for the chairman to enforce punishments for "dishonourable questions," thus disallowing "I have never cheated on my current partner" and other such mood-killing declarations.
Aftermath
Hopefully no-one has been too embarrassed by the game, but if anyone has, it is usually a good idea to ensure that what has been said goes no further. Prizes can be given for the best question, the most exciting person (i.e. The one who drank the most), the dullest person, and the Honesty Prize if anyone admitted to anything truly impressive. It can also be a good idea to follow the game with another which will enable any scores to be settled without anything further being revealed. Converting Mornington Crescent into a drinking game works exceptionally well for this, whether or not those present are aware of the rules.
1Note, it is possible that some people will be drinking anyway, after all, they may be thirsty, they may not be concentrating, they may have been out of the room when the game started... their protests that they have never in fact slept with their boss should be dealt with by the chairman. One way to avoid such instances is to insist that all social drinking be performed with the left hand, whereas all in-game drinking be performed with the right.
