O'Brien, O'Driscoll and O'Connell all feature in this year's edition.
It's become
a fixture in the build-up to the tournament, and once again we have Twitter user
@WelshDalaiLama to thank for this year's update to his Six Nations drinking game.
There are plenty of references to the northern hemisphere nations' dismal World Cup results, including a drink for every time England kick to the corner and Paul O'Connell's retirement, while old favourites like the Eddie Butler montage and TMO referrals make a welcome return.
Of course, we wouldn't dare try this ourselves, we value our livers far too much for that.
