You can't make an ass out of yourself all in one area, therefore, your friends should lead you around from bar to bar attaining as many free drinks as possible. No bar will support your habit all night long. After your 21st bar, you probably feel kinda whoosy and are wondering if you actually know the people around you. That is why they have cameras and will remind you of all the events when you return to your normal state of being days later. A good group of friends will probably see that you get home all right and that you sleep with your face in a trashcan, but a better group of friends will set you up with that girl across the bar who is also celebrating her farewell to whiskey virginity.
Life is so beautiful.
Happy Shafty 21 to all you out there, your number is coming up soon.
