For those who want the hydrating image, but not the effect, I present Smirnoff's latest concoction, Smirnoff Source, which is basically alcoholic spring water.
From the mouths of wiki...
The newest product from Smirnoff is Smirnoff Source, an ultra-premium beer-alternative created with alcohol and spring water released in May of 2007. It is citrus flavored and lightly carbonated with 3.5% ABV. It comes in pint bottles (20oz) only. Despite the lower-alcohol content, one 20oz bottle of Smirnoff Source contains more alcohol than a 12oz bottle of many popular American beers.
You have got serious problems if you need a lil kicker in your spring water.
