This is a television advertisement for Mountain Dew Game Fuel: World Of Warcraft. I don't want to spoil it for you, but I'm going to: two chicks turn into World of Warcraft characters and start battling right there at the grocery store checkout. Obviously, I would do them both. AFTER transformation ;)
Thanks to naas, who once Chaos Bolted an old lady in the face for cutting in line at the checkout.
