The vitamin drink Oronamin C, friend to hungover salarymen everywhere, launched a campaign today where one lucky person an hour, for 73 hours, will each win 50 bottles of the sweet and sour beverage. The catch? Contestants must install a Facebook app, "like" the Oronamin C page, and fill out a simple form. Yes, it's a marketing ploy for the company to gather information and boost its Facebook followers, but giving away that much Oronamin (3,650 bottles in total!) is still pretty cool.

What's the deal with the number 73, though? It's a play on the Japanese spelling of the popular drink, where 7= na(na) and 3=mi. By 1 p.m. today, they will have already given away 650 bottles. A lucky 60 people still have a chance to win, so if you're interested, start by "liking" Oronamin C's page, and then start thinking about where you'll stash all those little brown bottles.
