I am interested in compiling a list of all the true rules of drinking. so please post any rules you feel are apropriate and their level of importance heres a few to get started oh and feel free to scrutinize mine i'll take your coments into consideration

cardinal sins (you keep suffering after death):
Spilleth not thy beer
Throweth away not thy half-drunken beer.
Thou shal not serve Near-Frozen Knat's Urine and most specially not Weak Near-Frozen Knat's Urine
Thou shalt know where to draw the line
If thou was assigned to bring the beer... thou must be never be late

Federal laws (carry the death penalty):
After a party all booze left in the fridge is the sole property of the thrower of the party
If someone shouts you a drink you are obliged to take your shout.
Not everything can be explained by saying "I was drunk"
Most things can be explained by saying "I was drunk and I have the hots for you"
Almost everything can be explained by saying "I was drunk and I have brain damage from being hit around the head by Wes"
Everything can be expained by saying "whaaaaaaaaaaaat???"
You shall not lose the bottle cap opener
You shall not throw up in the main party area... theres a designated area for that
who ever gets drunk first shall spend the rest of the party dancing to the entertainment of the all the others
it is fair game to lead the drunk out side on the street and see if they can make it back in alive
Any guy found to be taking advantage of drunk chicks shall be given a good beating
Any chicks found to be taking advantage of drunk guys shall be applauded and encouraged
If you can remember it you have to take responsibility.
If you can't but someone else can you still have to take responsibility.
If no-one can remember it the last person to deny having done it takes responsibility.
Members of the opposite sex have a tendency to be much more attractive at the end of the evening, than they will be the following morning

By laws (shit off everyone around you):
Know what drinks your friends really hate and don't offer them it
Don't ask people why they are getting drunk, you should either already know or find out later
If you do some thing stupid when you are drunk you are not permitted to whine about it when sober
if your friend does something stupid while drunk you are allowed to tease them mercilessly
Any information leaked while drunk whether incriminating, embarrassing or otherwise is considered to have been obtained fair means and thus is free game
If someone is chundering force feed them water
If you are chundering it is your own stupid fault
Beer bottle tops may be used to awaken sleeping fools

Things you will forever regret doing while drunk:
Starting a sentence with "this may sound gay but..."
Making out with a tree
Finding all the hot chicks in the room and tell them they are beautiful and ask them to marry you.
attempting to your friends rather large dog like a horse

as I said please add to this list I'm hoping to have a big one to stick on my fridge at my next party and whatever you can do will really help EDIT: the ones posted below have been added as have somemore by me
