Go to your nearest liquor store and find something that has a 40oz. Get everything else of all shapes and sizes of that alcohol. Malt liquor has the best variety. For example get a Colt 45 40oz, 32oz, 24oz, 22oz(can), 22oz(bottle) 16oz(can), 12oz(can) 12oz(bottle). It is equal to drinking over 4-40oz. Start with any of them and drink them all and the first one done wins.
