These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
There were also football commentators and referees, which were the target of the odd Take That. Like in one episode where El Chavo and Quico are playing soccer, El Chavo allows Chilindrina to play with them as long as she plays the commentator. When Quico argues that Chilindrina knows nothing about soccer, Chavo simply replies with "Exactly!"
Big Lipped Alligator Moment: In an episode of 1973 and involving Don Ramón working as a barber, the plot suddenly comes to halt near the end and, literally out of nowhere (Seriously. The scene at the time, taking place in the barber shop, quickly fades away in a very out-of-place, psychodelic way), changes to the whole cast sound and well in the neighborhood, talking about Mexico and the world's current affairs (for the time). The scene soon changes back to the previous scene in the same colorful and spiral manner.
Don Ramon is legendary amongst Latin Americans as the funniest character on the show, to the point of Memetic Badass status. Popular items include T-shirts with his face superimposed on Ernesto "Che" Guevara's!
It is said that Quico's popularity was bigger than Chavo's. The tension provoked by this situation led to Carlos Villagran leaving the cast, followed by Ramon Valdez.
La Chilindrina was and still is amazingly popular. Actress Maria Antonieta de las Nieves went on to appear as La Chilindrina in a movie, a soap opera where she guest starred for several episodes, and even had her own very successful circus.
El Chavo was extremely popular over all of Latin America, but it's brutal in Brazil.
Also worth noting that is by now much more popular in the rest of Latin American countries than Mexico.
Hollywood Homely: Played right: you can be surprised by how pretty Florinda Meza and Maria Antonieta de las Nieves really were out of their costumes of Doña Florinda and La Chilindrina. Watch them in El Chapulín Colorado and be amazed.
Doña Florinda's makeup was so over-the-top, it's hard to believe how gorgeous Florinda Meza is, even today.
Memetic Badass: As of lately, Latin-based * chan imageboards have taken Ron Damón (not Don Ramón, Ron Damón - based on how Chavo pronounces his name) as some sort of avatar of Mexican badassery. Just go to any * chan, write "hora de ñ" and see the Ron Damón macros (and racist comments) cascade in.
Rescued from the Scrappy Heap: But there are many heartwarming moments with her, like the Christmas episode, the Churros episode, that give some positive light to her.
Values Dissonance: Obligatory when considering how old the show is. Don Ramon's hitting Chavo as part of the running gag or it being implied many times that he spanked Chilindrina. Certain episodes have everyone getting extremely disgusted when a confusion leads them to think that Don Ramon and Jirafaleswere in love with each other. Not to mention, the show was set and videotaped in the Mexico from The Seventies. Mexico is a very conservative society, even by Latin-American standards.
The Woobie: Chavo is this sometimes, mainly in the episode where him is Mis-blamed for theft, ostracized by everyone and leaves temporarily. It traumatised several generations: seeing everyone calling him a thief at his face is pretty hard to watch.
