Anyone that watched Family Guy last night has learned that energy drinks are fuel:

Brian: Whoa, whoa you're adding kerosene? That's insane! That'll destroy your body, Peter!
Peter: Kerosene is fuel, Brian. Red Bull is fuel. Kerosene is Red Bull...
Brian: That drink will kill you, Peter.
Peter: Whatever kills me will make me stronger.

Well, it is kinda true, Four Loko which was pulled from the shelves last year has found a new life, in the gas tank of your car. It is being recycled into ethanol and blended with gasoline. Could you skip the middle man and pour a few cans right into your tank? Probabaly not the best idea.
