I suspect they fell for the same urban legend y'all did
'Cuz when anything is repeated enough times, it has a way of becoming "fact." Case in point: years ago, when Johnny Carson was host of the Tonight show, he had a well-known advocate for the homeless (his name was Mitch something, he was in the D.C. area, and died not long afterward from a hunger strike). On the show, he stated that there 10 million homeless in the US. The press immediately picked up that number...no one did any research, no one challenged it...from then on, 10 million became the number of homeless. That is, until the 2000 census couldn't turn up more than a few hundred thousand, despite humongous REPEATED efforts on the part of a zillion homeless advocates to find more...till finally they had to admit that they'd prob'ly found at least 90% of 'em. Everyone likes to make a good story better...and the harder anything is to prove or disprove something, the more credibility it's given. Btw, I couldn't find any mention at all to male drowning victims found with fly open on Snopes, despite trying every search word/phrase I could think of....which surprised me, 'cuz it's been repeated so often by so many people for so many years (at least 25 that I know of), that surely Snopes would have heard of it--they seem to have heard about everything else...but apparently not that one. I dunno whether that's evidence that it is fact, or evidence--as I've been told for years--that it IS urban legend.
