- Accidental Innuendo: In one very old strip, Dagwood is explaining to Alexander about how to make a Dagwood Sandwich, explaining what each ingredient brings to the whole. He explains to Alexander that "The sausage makes it gay". Yes, Dagwood, I believe it would..... but not these days!
- Memetic Mutation: "Don't touch that dial!" originated as a Catchphrase that CBS announcer Hanley Stafford used to open the Blondie radio show each week.
- Older Than They Think: A few visual gags actually came from this:
- Protagonist Title Fallacy: While the strip is named "Blondie", Dagwood is more often than not the centric character in a strip.
- Retroactive Recognition: "Blondie, stop this crazy thing!"note
- Uncanny Valley: Blondie, Tootsie and Cookie never change facial expressions.
- "Weird Al" Effect: The strip started out as a parody of the many "pretty girl" melodramas (like Tillie the Toiler) that spread on the funny pages during the late 1920s and early 1930s, but became forgotten in the ensuing decades.
- Covered Up:
- "Hanging on the Telephone" is a cover of a song by The Nerves, who were an obscure band. It had already appeared on their first EP. They were friends with the song's writer, Jack Lee, who agreed that Blondie should cover it. He also gave his song "Will Anything Happen?" to them.
- Few fans were also aware that "The Tide Is High" (originally by The Paragons) and "Denis" (originally by Randy & The Rainbows) are covers. When Atomic Kitten covered the former, many assumed it was a Blondie cover (if, ironically, their version wasn't also victim to this trope).
- Face of the Band: Deborah Harry.
- Germans Love David Hasselhoff: They are much more popular in the United Kingdom and Europe than they are in the United States. When they started, American audiences didn't know what to make of them, feeling they were too pop for punk audiences and too punk for pop audiences, plus there was the fact that they had a female singer, which was not common at the time, and meant Blondie were basically known as 'that band with the hot singer' (especially in their CBGB days). In the United Kingdom and Europe, audiences seemed to appreciate punk, pop and other genres in equal measure. To this day, Blondie are considered the quintessential pop band in the United Kingdom, whereas they are known mainly for their hit singles ("Heart of Glass," "Rapture," etc.) and their connection to CBGB's in the United States.
- I Am Not Shazam: Blondie is the name of the band, not a nom de plume for Harry herself. According to the documentary "One Way or Another", they took the name from what truckers shouted at Debbie after she bleached her hair blonde.
- Memetic Mutation: "Blondie is A GROUP!"
- Misattributed Song:
- A considerable number of songs are attributed to Blondie when they are actually by Kim Wilde, including "Kids in America" (which has also been attributed to Nena, The Bangles, or The Go-Go's), and Wilde's '80s version of "You Keep Me Hangin' On"note (which has also been attributed to Belinda Carlisle from the aforementioned Go-Go's, Kylie Minogue, Madonna, or Tiffany).
- Subverted with "Rush Rush" from Scarface (1983) and Grand Theft Auto III. It's not by Blondie, but by Debbie Harry as a solo artist collaborating with Giorgio Moroder.
- Narm: Debbie Harry's rap on "Rapture" is utterly ridiculous. The delivery is silly already, but the lyrics don't help:"The man from Mars
You go out at night, eatin' cars
You eat Cadillacs, Lincolns too
Mercury's and Subaru's
And you don't stop, you keep on eatin' cars"
- "Seinfeld" Is Unfunny: So many Alternative Rock (especially in the modern Post-Punk/New Wave Revival) bands have been influenced by their look, attitude and their whole "poppy, punk-influenced rock band with a female singer" schtick that many younger listeners may hear their music and wonder what's so special about them.
- Tear Jerker: The song "Susie and Jeffrey" is about a young couple getting married, the song has an eerie tone to it that implies even without the fatal car accident at the end, their relationship was doomed.
