We've covered a lot of luxury items on Neatorama.... like the world's most expensive book and whatnot. Usually the trick is to add gold, diamonds, and the like to whatever it is you want to make expensive.
This is no different: Tobias Wong and Ju$t Another Rich Kid created the Gold Pill, guaranteed to make your poop glitter with gold! For $425, these pills containing 24K gold leaves will "turn your inner most parts into chambers of wealth!"
