In Ireland, in recent years there is a tradition of doing a pub crawl / bar hop called the 12 pubs of Christmas. You got it, there's 12 pubs. It's generally done last day of work before breaking up for the Christmas holiday and starts at 6pm and finishes at 12am.
Over the last year or two this has extended into a Saturday night thing with friends.
It also now involves Christmas jumpers! The gaudier the better!
I cheated this year and only had two drinks rather than 12. I had Basket Brigade on the next morning at 9am so I just would not have been able to get up had I done the full 12.
