YMMV: I Love Lucy

  • And You Thought It Would Fail: CBS initially responded to Lucille Ball's insistence that Desi Arnaz play the husband in her TV show by saying they weren't sure if audiences could believe that a celebrity like Lucy was married to an obscure Cuban bandleader. In response, Lucy and Desi gave a vaudeville tour across the country. The tour became a success, proving to the networks that a TV show of the duo would be huge.
  • Broken Base: CBS aired colorized versions of the Christmas Episode and "Lucy's Italian Movie" in December 2013. This didn't mark the first attempt to colorize I Love Lucy, but it did prove divisive among viewers: Some liked the fact that the picture looked more natural than that of an early-'90s colorized print of the Christmas episode, and felt the color added to the humor. Others disliked the fact that the picture still looked less natural than the original monochromatic versions, and couldn't stand the mere thought of altering the picture in so drastic a fashion.
  • Crowning Moment of Awesome: Lucy once did the Mirror Routine... with HARPO MARX!!! Here. Followed shortly by a second CMoA: Harpo plays "Take Me Out To The Ballgame" on the harp. Gotta see it to believe it.
  • "Funny Aneurysm" Moment: Any episode that involves a joke about philandering, or Lucy and Ricky's marriage being in trouble, or both.
  • Harsher in Hindsight: Watching the episodes 'Lucy Meets Charles Boyer' and 'Lucy and Superman' are particularly saddening, knowing both Boyer and Reeves ended their own lives.
    • From 1951-1954, Phillip Morris cigarettes was the show's only sponsor. Desi Arnaz died of lung cancer at only 69.
  • Hollywood Homely: Ethel, and to a lesser extent Lucy. While both were never referred to as ugly, many times there would be a reference to how unattractive the two are (especially Lucy) when put next to the younger, fancier Marlyin Monroe-esque types that occasionally appeared in Ricky's shows. This is ironic as both Lucille Ball and Vivian Vance began their careers as models and showgirls.
  • Hollywood Pudgy: Urban Legend has it that Vivian Vance (Ethel) was contractually obligated to remain overweight, though there isn't evidence of it being true, especially since Ethel only looks fat in comparison to Lucy. Get her alone and she's rather thin. Reportedly, Ethel was supposed to be on the heavier side, but Vivian Vance fought against it, arguing that if Fred calls Ethel a fat old bag when she's really overweight, the scene would fall flat because you'd feel sorry for her. Whereas when he calls her that when she clearly wasn't fat or ugly, the dissonance of it instead makes it funny.
  • Memetic Mutation:
    • From The Young Fans episode: "Keep jiggling, Peggy."
    • "Are you tired, run down, listless? Do you pop out at parties? Are you unpoopular? The answer to all your problems is in this little bottle!"
  • Seinfeld Is Unfunny: This show invented the modern sitcom, and every single sitcom that has ever existed since has borrowed something from the lexicon it created, to the point where things that were groundbreaking in the '50s are not even noticable, let alone edgy... unless you are blocked by the Nostalgia Filter. And somewhat ironic for this trope, both the real and sitcom versions of Jerry Seinfeld have proudly noted having NEVER watched an episode of "I Love Lucy" in their lives.
