There was a great Dilbert that had his mum asking him the "if everyone jumped off a bridge, would you?" question. His response was along the lines of "if they all came back and told me how awesome it was, yes".
Thank you, this puts a great twist on the situation.. basically saying that if all of his generally smart, sane friends all of a sudden jumped off a bridge, most likely there was a REALLY good reason behind why they did it
