Lore has it that the original "Gatoraid" energy drink has that for a name because it was created by the sports medecine folks at the University of Florida ("Gators") for use by their football team while training in exceptionally hot weather.

I have no idea if they got rich, get royalties or sold the rights to someone else.

Just an interesting tidbit of useless knowledge. This thread has turned out to be quite a bit of fun.
