Base Breaker: Tim Conway's endless antics to crack up his co-stars. While they're one of the most loved and well-remembered part of the show to this day, during the show's run they received a lot of criticism. The show had very smart, funny writing, and deliberately messing with the sketches to make everyone break up was seen as disrespectful to the writers and cast. Not helping matters was Conway's taking advantage of the fact that each show was filmed twice, with the better take making it to air; if the first taping was deemed good enough for airing, Conway took that as carte blanche to go wild on the second taping, meaning only one studio audience got to see the sketch the way it was intended to be played.
One "As the Stomach Turns" skit gives an unfortunate double dose, the first being the storyline of Marian's only daughter having apparently been killed (said daughter in the sketch does return, having actually survived, but still...).
"Disaster '75" has Harvey Korman playing a bomber who can't find work because he "used to be in charge ofFriday nights on ABC", this reference having gone out-of-date when ABC introduced its famous TGIF lineup in 1989, ended it in 2000, revived the format in 2003, then ended it again in 2005, effectively recycling itself.
One sketch has Harvey Korman and Tim Conway as Japanese chefs, invoking every Asian stereotype you can possibly think of. Astonishingly, this sketch still airs in reruns.
One early sketch about airlines in different countries has Carol and Nanette Fabray playing Japanese stewardesses in Yellowface and kimonos speaking Engrish. Ironically, the show only got negative mail about another segment in that sketch, portraying the Eastern European airline as dirt-poor and run down.
Another early sketch had Carol and Imogene Coca as two opposing politicians' wives, with one blasting the other for making the faux pas of seating George Wallace next to Martin Luther King Jr. Nowadays, the bigger problem would be that she was seating George Wallaceat all.
