A random person said:
I'd kill a man (I don't even need the bar to motivate me).
Coo...er, Klondike Bar for whoever gets the reference.
Could it be?...Family Guy?
As for what I'd do for one, I honestly have no idea. I've never had one, I'm not even sure you can get them in Britain. From the sounds of things they sound like brand name choc-ices.
But for the sake of argument lets say that for a Klondike Bar...I would travel to America...and go on a horrible, gruesome and bloody rampage of criminal assault, murder, kicking puppies and juggling until someone listened to my demands and gave me one.
