Worst I've ever been was a rugby thing in Cardiff. Now, I'm not a rugby fan but a couple of mates from Bristol talked me into going, said the atmosphere is great, different to footie, more relaxed, can drink in your seat etc.
Of course, we had cans on the train going over, beers before hand and beers during. Literally no idea if the games were any good. Was fairly noisy and rowdy. There was beer too. Can't even recall the name of the tournament. Think it was in the millennium stadium. My mate nearly got chucked off the train at Bristol Parkway for being a bulb with the ticket inspector ('lost'his ticket, accused the inspector of stealing it, realised he'd dropped it on the floor). That's about it. Probably a good one to get booze amnesia for, rather than one you are arsed about.
The Six Nations is great, but again I can't really remember too much of the games I've been to as it's typically been an excuse to go on the piss for a few days.
For example, I went to watch Scotland versus France at Murrayfield at it was so cold, and if you've been to Murrayfield you'll know it's a concrete shell.
To get a pint you have to walk out onto the grounds around. Knowing it was going to be cold and we'd already drank a bit, I prepared two hip flasks of scotch.
Unbeknownst to me, the rest of the group had has such a fantastic idea. We all ended up drinking our own flasks after being on the ale all day.
To this day, I still don't remember any details of the actual match. Another one was when Scotland played Wales at the Millennium Stadium.
We always stayed in Swansea, so we drove down on the Friday, drank a shed load of ale till the early morning, got up and carried on throughout the day.
Anyway, I remember more from the evening of the game when a mountain of a woman knocked multiple male bouncers out in a club rather than the game.
