I’ve never seen a patent on a technique for selling mattresses. And, perhaps I’ve been awake too long, but is this David Hasselhoff in the illustration? Knight Rider using jiu-jitsu to sell a mattress? Only the Hoff could be such a bad ass. He will grab you buy the arm, measure your resistive force, and send you home with a Posturepedic. Assuming of course, that once he’s laid hands on you, you have any resistive force left.
