Joker Mad Energy Drink was originally made by Hansen's beverages and was once discontinued.

It looks like Circle K convenience stores are now making it and distributing it throughout their chain of stores. 

There were a number of formulations including Joker Mad Energy Lo-Carb (sweetened with Ace-K and aspartame), and Joker Mad Energy + Juice, but it looks like there are some new variations.
