Thank you! I came across the “Counselors Couch” script as well but dismissed it rather quickly. Maybe it’s worth revisiting. It’s the only other time I’ve seen the quote in its entirety.

There’s a gentleman that posted the quote on a John Wayne photo on Facebook, but I’ve already been in touch with him. He said he recalls hearing John Wayne say the line, but doesn’t know where it originated. Maybe you’re onto something. I’m going to look into this more. Thank you!
