what a load of rubbish!!
if it was that cold for lake to freeze then they would prob be in hyperhermia (sp)
if the ice was that thin on edge on hole then you wouldnt stand there like ronnie did before diving in, it would all crack
once out, they should have been dripping wet, and you certainly WOULDNT cuddle a premature baby when you have been in freezing cold water!!
i know its not real, but surely they could have made it a bit more life like!!
