IKEA has probably dealt with its fair share of customers that want to claim a warranty but can't produce their receipt, because, to be fair, receipts were made to be lost or discarded. So the Austrian division of the furniture giant made this cheeky ad about creating a stainless steel receipt that will last as long as the furniture does (or, hopefully, even longer if it's supposed to actually come in handy). It's not clear if this is a real thing that's going to exist or just a fun commercial, but...not the worst
