Johnny Carson album

[Laporbo]

I'm on a quest. Maybe someone here can help me.

Sometime in the late 80s or maybe early 90s, Johnny Carson did a "bit" concerning Elvis. He often did this bit from his desk where he would show a mock-up of a fake album and make some kind of joke about it. Well, this night he showed a fake Elvis album.

Anyone remember that? And, bigger yet, anyone have it on video?

Thanks for reading.

No, I don't remember that; I do remember David Letterman doing something similar, but they were real albums - Leonard Nimoy or Telly Savalas singing, instruction type albums.
And there was the one where he played Michael Jackson singing "the chair is not my son".
