749,250 bottles of beer on the wall....

So, you're planning a holiday party. And don't now how much booze to buy. (Oh, and don't invite Susan Cheever!) Evite has the handiest of handy-dandy calculators to help you figure this out! So, say the party will last 999 hours...with 999 heavy drinkers into liquor and beer. So what will you need? Well, you can see for yourself -- roughly 750,000 cans of beer! Off for the liquor now. See you in the emergency room!
