But Oz never did give nothing to the Tin Man
That he didn't, didn't already have
And Cause never was the reason for the evening
Or the tropic of Sir Galahad

Just in case you didn’t recognize the above lyrics, they’re from a very famous pop song. 

Along the route of my current walk, is a Tin Man, that I pass every morning.  He never says much, but the owner who built him, definitely has a fantasy world where the Tin Man lives.  There was another Tin Man in town, but his owner died and her children happily carried him off to some unknown place.  Maybe Oz.
