since coffee does not go well, I actually resort to these things in emergencies... mostly long drives where I get tired but don't have time to stop off and take a nap.

The only one I like is "Bookoo", simply because I used that word as a slang adjective (it's a bastardization of the French word Bohkoo (sp?), meaning 'alot') before the drink came out. My friends gave me shit, since i sorta make up words alot, but then I found the drink in a gas station and it just cracked me up.

Oh, and Sparks is SHIT! It's like someone simply poured a beer in a generic energy drink... disgusting...
