I was surfing through the channels the other day and came across this infomercial. The company and product True Back has this spinal back relief product that you lay on.

I think this company had been watching the Simpsons way too much lately. Because on an episode of the Simpsons Homer accidentally creates a back pain reliever from a metal trash can. It acts just like this, in that you lay on it and your vertebra line up with the ridges. I don’t know if they got the idea from the show or not but I thought it was pretty comical.
