Good Gatorade story:
Keith Jackson (the storied college football announcer a couple decades ago) did a commercial where he said the Florida Gators had a secret weapon in a big game - Gatorade - which was from a nutritionist at UF. he said on the commercial how Gatorade gave the Gators the energy they needed to win the game.
Later I saw an interview with one of the players and he said nobody actually drank it - it tasted like p!ss. They just poured it out and drank water. Still, once they added a bunch of sugar to it - it got popular
