Why u need to drink beer

Saw these when i was away from home, in other parts of Asia...

Punchline:
Water is PRECIOUS!
Save Water, Drink BEER!

Side note:
People who drink, get drunk..
People who get drunk, go to sleep..
People who go to sleep, do not sin..
People who do not sin, go to heaven..
So.. SO LET US ALL DRINK and GO TO HEAVEN!!
