Ok ok ok! Before you say this is off-topic let me explain. Was watching TV and a commercial for the movie 'Taking Woodstock'. There was a quick scene of a guy dumping something into a pool. His son shouts 'Dad! Its Bleach!' And his Dad responds with 'Yeah but its disinfecting'..
Duhee!! Bad script writers for not knowing you put BLEACH into a pool! It is amazing how many people don't realize what bleach is.
