Tongues do GOOD

The tongue... the most versatile muscle in your body. It never tires, it's always moving, and it works whether you're awake, asleep... or even paralyzed. Introducing the Tongue Drive System - a way for tetraplegics to live their lives without 24-hour assistance. They can operate their wheelchair, computers, phones, lights, television. They will soon be able to operate a car. All through the use of their tongue... and one strategically placed tongue piercing.
