Obviously there are so many different permutations of rules etc...

I think some of the core rules are the same yeah?
- No saying drink
- No pointing
- Left hand consumption only

But we also have other ones, for example if you say the word 'mine' you have to do 10 press ups and if you say the word 'game' you have to do 10 sit ups. So you hear a lot of people saying 'it belongs to me' and 'gamma'.

So many other ones too of course....so what weird rules do you guys use?
