Some people will pay any ridiculous amount of money for something that's one-of-a-kind. Case-in-point, in 2006, somebody once put a piece of "holy" toast that somehow had the portrait of Virgin Mary on it up for auction on eBay. It sold for $28000 - That's a hella lot of money! Yes, someone actually paid top $$$ for an old piece of stale bread. People caught on to the trend and started using "toast" as an art canvas, with all kinds of images burned into them, which magically started popping up almost overnight on eBay, and most sold for nearly nothing. That original piece of toast is likely fully decomposed by now. Stoooopid buyers...
