- They Changed It, Now It Sucks!: Probably when the show kicked out the third couple in 1956, and DeSoto followed around 1957-58. The last few seasons just don't feel the same.
- It probably didn't help that the duck was put into semi-retirement* near the end of the run.
- Tough Act to Follow: Buddy Hackett and Bill Cosby learned that successfully remaking the show is impossible without Groucho.
