This is a hillarious video that shows how to use your skull to increase the signal of your car locking remote. Apparently if you hold the keyless entry remote to your chin, open up your mouth and then try to unlock your car, it gives you an increased range. I have tried it myself and it does work, the only thing I am not sure about it is if it works that nicely or makes that big a difference in an open parking lot than an enclosed one. In the underground parking lot where I tested, it definitely increased the range by a few feet! The video itself can be found here:
