Slinky's Father, Mr. Walker. These ads never admitted the one thing about Slinkys no kid can forget: they left your hands smelling like metal and oil. Also, once they kinked up, they were useless. Like a horse with a broken leg, all you could do was put them out of their misery. I'd wager every Mr. Walker suffered the same fate; once it could no longer make it down the stairs, kids just pulled it and pulled it and stretched it until it was a useless jumble. Then they sat around and waited for someone to invent the Spyrograph.
