I find it funny (as in sad and pathetic) how many people out there all of the sudden are experts on water poisoning (and seemingly have been for years and years), and how quick they are to call the lady an idiot for doing this competition in the first place.
I for one had never heard of water poisoning, and could have easily entered into a competition like this one, without any suspicion that my life was in danger from drinking water, and would have (not unreasonably I would have thought) assumed that proper precautions were taken to ensure my safety.
I think it was very clear from the attitudes of the DJ's and the final outcome that they indeed were negligent. I am glad they lost their job, and I do believe the station should be held liable for not requiring that the proper safety of those participants be met.
