Koreans have a really heavy drinking habit, and while things have changed a lot in the last decade or so, still most of the men define "having a good drink with your fellows" as either drinking through the night 'til morning, or everyine knocking themselves out and waking up in a place they don't recognize.
I remember when I was in college, and we had a spring festival in campus. Ofcourse, since any festive activity immediately associates with drinks and drinking contests, so the night quickly grew rampant.
I remember putting down about 3 bottles of the nasty, typical Korean liquor called 'soju' - which is not as strong as whiskey or vodka, but really nasty and squirmish stuff when your brain drowns in it. Then after entering a drinking contest with a bottle of tequila I passed out sometime around midnight, and can't remember what happened.
The next day, I woke up, with morning sun so brightly blazing. I was lying in the campus bench, and couldn't move. To my surprise, I was tied up to the bench with adhesive tapes as if I've been abducted or something.
There I lay on the bench, my head hurting like hell, with all the students walking by scurrying around the bench I was in, glancing at me if I was a roadkill or something. I was infuriated - who could have done this to me? How humiliating.
Then, after a while, one of my friend showed up, looking pretty much terrible, since he was also a participant of last night's madness. He unwrapped the tapes and explained to me that everyone was so drunk that the guys who could actually manage to walk on their two feet, couldn't take two steps without stumbling. I was zonked out and sleeping, and all the other guys were pretty much braindead.
In their drunken stupor, they were worried that I'd wake up in the middle of the campus and go bump into tree or wander off into a road and get hit by a car or something, so being such good friends, worrying about me, they decided to just tape me up to the bench so I couldn't wander around hurt myself while drunk.
I was actually kind of touched. I'd have been a lot more thankful to my friends, except I had to go pee, and I couldn't get out of that chair for three hours after waking up.
Ah, a typical day of Koreans and alcohol.
