People that live in glass houses shouldn't throw stones ; who said it what do think about it?

Question

I heard it in the early sixties from Mr. Glass himself.

Answer 1

It is what is called in linguistic terms an "adadge" or sometimes a "maxim"; sometimes a "proverb" and it was said by someone a long time ago and was so "hitting the nail on the head" that everyone started saying it when they wanted to tell someone to stop judging someone else.

Answer 2

Billy Joel said it. What I think: Not his best album.

Answer 3

i think its a pretty obvious statement and doesnt usually need to be said.
