There are fake Jawbreakers, believe it or not. There are even a couple YouTube videos that demonstrate functionality and lens swapping between the real and fake models. These fake models are really only revealed on close inspection, such as lack of unobtainium on the earstems, inconsistent details or contours, etc. But the major stuff like jaw motion and earstem adjustability are all there and will fool someone who isn't looking at those finer details (I have even seen a fake Jawbone with a working jaw). Granted, many of the fakes are usually just painted to LOOK like they have separate components and don't actually move, but there are enough fakes out there that actually work so functionality alone is no longer enough to eliminate a fake.
