I whip a 100 mph shot at you with my lacrosse ball and send you flying into the lake from which you just sent someone, and if any of you guys are looking for a hole in my plan, the ball bounces off your head and comes back into the mesh of my lacrosse stick
Hearing of your miraculous head re-generating feats, you are thronged by zealots and hangers-on who ceaseless prod you for the meaning of life, to cure to their ailments, pleading for spiritual salvation, and begging you to tell them the name of the next American Idol contestant to be kicked off. Try as you might to manage the situation, you finally become overcome of being constantly bombarded by questions, and decide to end it all by removing your head (again). Whereupon, your would be followers, thinking that you were a false prophet, burn your corpse and scatted the ashes to the four winds.
... but I'm still not going near that freakin' hill -- even though I bid at auction for it against Lack (my plan had been to lease it out as an absentee owner) -- so the hill goes to...
Well Voldy, you may never die, but there's not much you can do without a body... and I destroy your seven Horocrux's and you turn into a flayed trash-can baby stuffed under the bench at Kings Cross. Leaving the Hill once again ownerless... until...
Yes - the sight of a dead flayed baby regenerating from out of thin air would be pretty freeky.
Fortunately for you, the kind souls at the Church of the Ungodly Lord of Wrathful Foregiveness find you and place you in with a loving family comprised of Tom and Mary Forthright who take you in, being that they are without children of their own (Mary was secretly a man in her past life and therefor lack the necessary parts to conceive a child). Unfortunately, the family dog, Fido, cannot resist the tasty aroma of your flayed skin and eats you, whereupon you possess Fido's body and are so content being a creature that can lick its own private parts, you live the rest of your life happily as the Forthright's pet, occassionally going for a walk to the hill where you leave little doggie presents for the new owner ...
Jackie Chan is indicted on animal cruelty after a full press public opinion campaign by PETA for Chanifying a dog. The Forthrights attempt to reclaim the hill from you, but are too frightened to confront a massive robot until one day you slip on a doggie "biscuit" left from the previous owners and your main drivetrain gets dislocated so you can't move. The Forthrights reclaim the hill and leave your paralyzed robot body on the lawn as a memorial to Fido, and there is much pidgeon crapping on your head...
