Fell asleep on a Tram that goes past my apartment in Vienna.
After midnight the trams change line. I ended up about 30k from where I was trying to get to at 2 in the morning.
A guy I used to work with went on the smash in London, got on the train with the best intentions of getting off at Didcot Parkway. Woke up at Bristol when the train terminated. Realising he had to be at work (near Didcot) about 6 hours later, the only option he had was a taxi, only cost him a few hundred quid. When he got back to his place, he discovered at some point in all the carnage he'd lost his keys, so went to work early and slept in his office.
Most people would learn after that sort of experience, he's done a similar thing a few times since then. Absolute animal on the beer!
As for me, I last got completely bungalowed 4 years back, on my 23rd birthday in Wolverhampton. Started power drinking at 5pm, went to Revs at 9, had a few more pints, did some shots, went to the pub across the road (the Royal London seems to ring a bell?) did some more shots, high-fived everyone in the pub, went outside, threw up all over my mates new shoes, fell asleep on the pavement, woke up at 9 the next morning...good times!
Now I very, very rarely touch alcohol. I work too hard to waste my time off feeling like death, I'd rather spend it DHing
