I've got to say, if it is an April Fools joke, it's not a particularly tasteful one.
And it certainly isn't funny.
Not only is it not funny in a general, most people wouldn't find it funny sense, its not even funny from a sarcastic, obnoxious, off-color, or any other less usual brand of humor sense. Its just not funny to the degree that I don't even see the point of such a joke.
That's assuming its a prank. I don't think its real because it reads way too much like an urban legend to me, but judging from the forwards my Mom sens me, I can believe the OP thought it was real. Maybe.
I'm also not saying that such an event is impossible. Just highly unlikely given all things consideration.
ETA: Man I really screwed that up. Amongst other things, "off-color" NOT "of color".
