Line #3 YMMV/WhatsMyLine


1	* FanNickname: Some fans weren't too fond of the 1968-1975 daily syndicated era of the show, thinking it was too much like Goodson-Todman's ''I've Got a Secret''. Hence, they have dubbed it as ''What's My Secret Line?''.
2	* GermansLoveDavidHasselhoff: The German version, hosted by Robert Lembke, ran from 1955 to 1958. A second run was produced from 1961 to 1989, when Lembke unexpectedly died, meaning it ran longer in its second version than the CBS and syndicated runs of the American original combined! It ran once more from 1999 to 2005.
3	* HarsherInHindsight:
4	** On the April 4, 1965 episode, John Daly said to the mystery guest that night, Maurice Chevalier: "I just hope that when I am 77 (sir, if you will forgive me), that I have your ebullience of spirit, your perennial and wonderful youth, and that glorious confidence". Daly died four days after turning 77 in 1991.
5	** On the November 2, 1958 episode, John Daly congratulated Mystery Guest Creator/RobertWagner on his recent wedding to Creator/NatalieWood and wished them a long and happy marriage. As both of their pages note, Wagner and Wood's marriage went through considerable turmoil and ended with Natalie tragically drowning in 1981.
6	* HilariousInHindsight:
7	** The interview with Creator/SeanConnery after he's identified on the October 3, 1965 episode. Now that we know he was tired of playing Film/JamesBond by that point, it's obvious that the whole time he's desperately trying to [[AdamWesting turn the conversation towards his other work]], only to keep getting roped back into talking about Bond.
8	** Robert Morse puts on a fake deep voice to hide his identity when he was the Mystery Guest on the March 12, 1967 episode, which sounds quite similar to how deep his voice really did get in his later life.
9	** As noted on the main page, [[Series/SesameStreet Big Bird]] was a mystery guest on one episode. Bennett Cerf's son, Christopher, would later become a prolific composer for ''Sesame Street''.
10	* QuestionableCasting: The appearance of actress Pamela Tiffin as a panelist on the March 12, 1967 episode. Commenters on Website/YouTube have called her one of the worst panelists in the history of the show, due to her poor gameplay and a number of on-air gaffes (including forgetting to introduce Bennett Cerf at the beginning of the show).
11	* RetroactiveRecognition:
12	** Colonel Sanders of UsefulNotes/KentuckyFriedChicken fame appeared as a guest on the December 1, 1963 episode as a "regular person" guest contestant before he was a household name.
13	** The September 16, 1956 episode opened with Creator/JacquesCousteau as the first guest. Since Cousteau was not a familiar name with the panel (Cousteau had signed in as Mr. X), all of them were stumped.
14	** When Creator/JulieAndrews was the special guest, they asked if she was known for her work in motion pictures, and she answered no. This episode aired four years before ''Film/MaryPoppins'' ended up making her a household name and completely overshadowing her Broadway career.
15	* SpiritualSuccessor: ''Identity'' (2006-07) was a [[WhoWantsToBeWhoWantsToBeAMillionaire supersized, high stakes]] version of the Who's Who game.
16	* TheyChangedItNowItSucks: Some fans of the classic series aren't too fond of the 1968-75 syndicated version due to the reduced emphasis on formality (panelists dressed more casually and were referred to on a first-name basis) and the demonstrations of new inventions (which was never done on the original series due to John Daly not being fond of the practice) making it too similar to ''Series/IveGotASecret'', to the point where they nicknamed it ''What's My Secret Line?''.
