Tom Kennedy on Plus managed to blurt out the answer to the Password Puzzle a couple times, resulting in a round that had to be thrown out but still aired.
Bert Convy was even worse at blurting out the password or puzzle answer on Super.
Super's set was almost ridiculously prone to breakdowns, few of which were edited out of the broadcast: the door behind Convy's podium sticking, the whole puzzle board accidentally being revealed, etc. Such bloopers would often send Convy and the celebs into long fits of laughter.
Fan Nickname: "Mr. Password" for Allen Ludden, as this was (in)arguably his best-known series.
The ABC version was sometimes known during the mid-1990s to early 2000s as "Password II", mainly to distinguish it from its 1960s predecessor.
Keep Circulating the Tapes: Most of CBS (daytime) was destroyed, with the last season put into syndication. ABC is even worse off, with only four episodes circulating and not many others held by archivists (plus the 1972 episode of The Odd Couple, which occasionally shows up on TVLand).
A Plus episode where George Peppard ranted about NBC's standards and practices, which he thought were like a "police mentality", never aired during the show's original run (didn't help that one of the puzzles used "Suck" and "Blow" as clues). GSN has aired it, however.
At one point, Charles Nelson Reilly was supposed to appear as a celebrity guest, but that particular week had Bill Cullen in his place...despite Cullen having appeared on the show only a few weeks before.
Half a Million-Dollar episode with William Shatner and Aisha Tyler was chucked due to Shatner bombing spectacularly in the Bonus Round despite having a Super champ as his partner. More info here.
"The only weird thing I can really think of to mention about that day, is that there was a woman, who was a champion on Super Password in the late 80's... who got to play w/Shatner and the other celeb... Aisha Tyler. It was such a slaughterhouse — she somehow made it to the end game with Shatner by some miracle, but he played so badly, that she could not even win at the $10,000 level. And they let her try twice. It was just pitiful. After the second attempt, all of a sudden they cleared the end game set up and started setting up for the next game, and she just... disappeared. No "oh wells," no goodbyes."
chad1m: (after posting the above) So, yeah. Even with the two tries at $10,000 rule, Shatner could not get five out of ten with his contestant in the end game. I couldn't imagine failing spectacularly with Shatner, TWICE, and then not having any TV time to show for it!
Sodboy13: "Congratulations for being so good at our game, you were able to overcome your complete idiot of a celebrity partner! Now, here's that same idiot again to harm you when it really counts."
BrandonFG: Yet another reason why the "highest scoring celebrity" rule is extremely flawed. I'm more surprised she was able to make it to the bonus game w/Shatner, unless she won by default.
TLEberle: I think it's really lame when a game show unilaterally decides that a contestant's appearance may as well have never existed for whatever reason they choose. Yes, I know. It's in the contracts and all of that. I also know that the example in question ended with no money being won. But part of the reason that game shows are interesting and exciting is because you don't know if someone is going to win or lose. (In the case of MDP, though, you do know when someone's last money round; by fail or bail, is coming.) Millionaire would be much less interesting if everyone got to $1,000. That's to say nothing of the contestant who tells all of her friends and family that she's going to tape an episode of Password, and has to come home and explain that her game was so utterly awful that it was chucked, and they replaced it with something else.
CBS' downfall can be traced back to the morning of July 11, 1966, when it was pre-empted in favor of a press conference by Secretary of Defense Robert McNamara regarding the progress of the Vietnam War; as NBC and ABC didn't give their news divisions the same leeway that CBS gave its news division, viewers began defecting to both NBC's recently-debuted Days of Our Lives and the debut of The Newlywed Game on ABC, giving the latter a larger sampling than it likely would've had otherwise.
Further problems arose when CBS' then-vice president for daytime programming, Fred Silverman (who actually openly hated game shows), wanted the show permanently moved to Television City and Mark Goodson refused.
ABC went into a massive gimmickfest on July 15, 1974, then changed to All-Stars on November 18 and drove even more viewers away. Unlike many other games which went to an all-celebrity format, ABC changed on February 24, 1975 to a big-money civilian-based format...but at that point, despite getting another 18 weeks, it was too late.
Plus and Super were both slotted at Noon, often getting screwed over due to local news. Both managed to thrive in the Noon slot, even with preemptions, mainly due to independent stations stepping in to air both programs in lieu of the preempting NBC affiliates.
Million-Dollar, while usually winning its timeslot, earned the ire of CBS for drawing the "wrong" demographic.
