Query: Why is this even being produced anymore?

A torture device disguised as a toy. How would you like to spend all day playing on the stairwell? Might as well go lick some dirty socks. I think my dog actually used to drag its bottom along the stairs to relieve a recurring rash. Hey, Ma, why does Slinky go down but not up? Who's the genius who found this at the scrapyard? Most toys in the 1970s relied on mankind's perverse craving for repetition and/or irritation.
