Sure, a USB thumb drive housed in the body of a full-sized rubber chicken isn't the most practical thing in the world, but it's still pretty awesome.
Picture it: you're sitting at a Starbucks with your computer. You realize you need some files you keep stored on a USB drive, so you pull a rubber chicken out of your bag. Everyone looks at you and thinks you've got a screw loose. You accidentally knock your coffee off the table when you adjust your laptop because the chicken is sticking out so far. Won't that be hilarious?? I see no downsides!
