in the music video for the song "tangananica, tangananá" , right at the end when the guarennes brothers are cleaning up after the mess they made , theres a lot of gross slurpy eaty licky sounds ! these only show up in episodes where this song is first place (so episodes 3 and 21 of season 1)
There's one brief scene of a mental institution in the Christmas special (season 2, episode 0) with the patients wearing straitjackets. (minutes 27:50-27:56).
not actual cannibalism, but in the song "huerfadrino" there is a character wearing hannibal lecter's mask while assuming that the singer's godfather was turned into his dinner. right after that, the singer implies that another cannibal ate him.
Played with in S4; Mario Hugo gets a noose intending to commit suicide but instead of placing it around his neck he sits on it and uses it as a swing "so he will be swinging on it till he dies out of boredom".
one example i can recall is the music video for "dracula, caligula, tarantula" , so watch out on season 4, particularily the episodes where it gets first place in the ranking top
theres like a whole bunch of screaming in "el fantasma del estudio" , both in juan carlos's green note and as a running gag (the episode at first focuses on the crew trying to find the source of a scream , which has different sources but sounds the same everytime)
In one of the episodes bodoque says "que te pasa vieja conchetumare" to a girl, wich translates roughly to "what do you want you old m**********r the curse word is cut short though
The show contains caricatures of black people, Asian people, and/or native people in the instances it chooses to show "human" puppets; one of the biggest offenders being season 2 episode 04 "Japonés" which contains a LOT of racism against Asian people in-general.
The show also contains LGBT+phobic jokes.
(Note: While, yes, there is a cultural gap between racial and LGBT issues in Latine countries and English-speaking countries, mainly the US, and that pre-2010s humor scene in Latine countries ran on being at least slightly offensive; it does NOT excuse this content.)
