One of the funniest thing I ever saw from the old Tonight Show clips was when Bob Newhart guest hosted on December 13th, 1976. He had Don Rickles on as a guest and during one of his jokes, he was using Johnny’s cirgarette box as a stamp and when he slammed it on the desk, he broke the lid! Johnny comes back the next night and finds the broken box and decides to raid Don’s live taping of his tv show C.P.O. Sharkey! This clip just goes to show how Johnny Carson was bigger than anybody and he could do whatever he wanted.
I just found a different site that has video of both nights in one clip, however, I’m leaving the one above because it shows a little bit more at the end. So if you want to see the night when the box was broken, watch the beginning of this video:
