tv's in a headrest for a single cab truck?

i dont get it, which is why i thought it was funny.........must be for the people that either follow behind or ride in the back of the truck.
i understand its a showtruck and if you think about it, a very wise investment. put it in some shows and win your money back + some.......shouldnt be that hard especially since its already got a good rep. being in magazines and whatnot.
