One question period had Carol tell a childhood anecdote in which she actually pretended to be a set of twins, complete with changing of clothes, etc.
Approval of God: Initially, viewers did not find the "Norma Desmond" sketches very funny, and felt they were an insult to actress Gloria Swanson (whom the sketches were a parody of). Gloria Swanson though appeared in one episode explaining that she thought they were hilarious.
Blooper: Of course a compilation of them was released.
Though many ended up in the final broadcasts.
Edited for Syndication: The intros with the audience and non-musical sketches were edited into the half hour 1978 show Carol Burnett and Friends.
Enforced Method Acting: According to Carol, the reason behind Ms. Wiggins's trademark walk was due to the fact that the skirt she was given was too large and walking that way was the only way to keep it from falling off.
Harpo Does Something Funny: Tim Conway either added his own embellishments or went completely off script during his appearances, sending sketches off the rails and causing the cast to break character to the delight of the audience.
Keep Circulating the Tapes: The first five seasons of the series (1967-1972) are co-owned with Bob Banner, preventing them from subsequent syndication and home video releases. With Banner's death in 2011, the outcome of this looked uncertain, until Carol Burnett and Time/Life announced a 2015 DVD release of select episodes from those seasons.
The bulk of the musical numbers have not been seen since the original network airings due to licensing issues. Eventually, a DVD collector's edition of the show which includes the musical numbers was released by mail order offering only 2 episodes per $19.95 disc, the extra money going for the licensing.
To put it simply, anybody with a pulse from 1967 to 1978 will have guest-starred on the show.
Hell, even some of the audience members were (and are) recognizable. Modern viewers will likely find Hannibal Lecter being in the audience rather hilarious.
"A Special Evening with Carol Burnett": Eunice's psychiatrist will be familiar to Golden Girls fans as the pyromaniac in the episode "'Twas the Nightmare Before Christmas".
Throw It In: The show would only do two takes a sketch, meaning even flubbed lines would get thrown in the broadcast.
Word of God says Miss Wiggins' nail biting was Carol's way of not breaking up at Tim's Mr. Tudball.
Un-Person: Sort of. The fact that Dick Van Dyke was an actual cast member during the last years (replacing Harvey Korman) is rarely brought up in documentaries or behind the scenes specials, and said episodes rarely air in syndication. Mainly because many people felt those episodes weren't very good, and that Dyke had no real chemistry with Carol, Tim, or Vicky. Even Dyke himself looks back at his time on the show with regret and embarrassment. On the other hand, Dyke does remain good friends with Burnett.
What Could Have Been: In interviews, Tim Conway said that in the 80s he was offered a chance to star in a Mr. Tudball spin-off. He declined because he didn't see much potential for storylines, plus the fact that Carol would not be playing Miss Wiggins.
