i've also seen an alcoholic energy drink called Sparx or maybe Sparxx in an orange can, tastes like sweetarts or something.
The bizzare (and awesome, imo) thing about sparks is, at least at the 7-11 where I first found it, it's cheaper than a comparably sized energy drink, and cheaper than a comparably sized beer. It's also high alcohol content I believe (10%? maybe 11).
Good stuff.
