Recently, I was shopping for new clothes when I came across an odd sign. It said that if you gave the store a pair of old jeans, you could get a new pair for free. Ironically, it was right next to racks of jeans with holes in them. For all I know, they might just take those old jeans, cut a few more holes, and put them back out on the rack. Yet for some strange reason that eludes me, people still buy them.
