Make like a tree and leave

COME BACK KID - Can any one tell me for whom this term was first coined for?
and what's the meaning of "Make like a tree and leave"?
Thanks

Never heard this, but it seems to me that it is a pun on 'leaf'. Trees make leaves, so behave like a tree and leave...

It's not a great pun, in my opinion, but there we go.

DFG

I don't know. But I'm betting it was a kid thing. Along the lines of, "Put an egg in your shoe and beat it."
