The Tonight Show with Johnny Carson with guest Don Rickles (1992)

I've posted so many episodes of The Tonight Show with Johnny Carson with Don Rickles as a guest I really can't remember which of these I've posted before (if any). Well, if this has appeared before, it's just like when Johnny was still on the air - a plethora of reruns (actually, i'm pretty sure I haven't posted this one before - surely I'd remember Don slapping Ed in the face!).
