Beerbelly Gets You Tanked

So, you're going to a sporting event or concert or children's dance recital. The bummer is that you can't bring any outside beverages in, no beer, no ice tea, no water. Whatever.
Beerbelly to the rescue! You can fill this bladder with whatever liquid of choice and wear it as a prosthetic belly. And you can drink to your heart's content. You need the sauce? Bring it with you, wherever you go.
Alcoholics, unite!
