How to use your head to amplify your car remote signal

Last year I wrote about the day I lost the car in a massive suburban parking lot. I tried setting off the alarm using the button on my keychain but the parking lot was just too darn big.

Thanks to Lifehacker I recently learned how to use my skull to amplify the signal. Apparently if you hold the keychain under your chin and open your mouth the signal will go further. If you lose the car as much as I do you might want to watch the video for a full demonstration (and proof!) on how this works.
