Ah! Elementary my dear Watson! Elementary!!
So ... listen up folks ... for this is an excellent question!!
You see, it happened one day when our hero was so bludgeoned by his noli me tangere heroine ... she tossed with single minded uncaring all those tokens of his love ... later that day, a Roc bird from days gone by happened to be flying overhead ... the glint of the bell attracted its attention ... from that far up it looked like an elephant ... rocs love eating elephants ... down it dived and downed the bell in one fell swoop ... its innards however were not too pleased ... the bell rang like crazy in its belly making its way to the other end ... right when it flew over the exact spot where the bell would be found - MANY months later, completely untrammeled by passing vehicles - it pooped! Buried deep in the excrement (thanks to which the bell had the softest of landings) was that bit of our hero's undying ardor ... over time the poop passed on, but the bell remained ... waiting to be reclaimed by the heroine who was, by now, deeeeeepppply in luuuuvvvvvv with the hero ... and the three would live happily ever after ...
Now wasn't that a fine believable tale?! No taller than what they're feeding us on KB surely!!
