I don't think there's anything ridiculous about drinking 2 quarts of water per day. I easily drink 48-144oz of pure water per day with the 48oz bottle I carry with me everywhere I go (http://store.nalgene.com/Silo-p/2178-0048.htm)
Saying it's necessary to drink that much water might be ridiculous, and perhaps that's what you meant, but I don't think there's anything ridiculous about the activity itself.
