Not sure if this counts, but one guy I knew would boast about how he never drinks water. It was a matter of pride for him that he only drank soda. I know he was lying because I'd seen him drink water, but better not tell him that.
That remembers me about this older video. It's in Romanian, but it says "stay away from water" and the images are from some sparkling water commercials presented as the consequences of anyone drinking water.
