Moral law! The drinker's guide
Was handed down by god
Sacred law for man to follow
Revere them as your own
Life's too short to waste your brew
It's plain to see-obey the rules
Thou shalt not waste and thou shalt not spill
Just drink your beer - Commandments
Thou shalt not puke cause there's no excuse
Just drink your beer - Commandments
Mankind was long deprived
Of the rules encased in stone
Ten written the rest were lost
