In Mexico, when someone is too stupid we say "no rebuzna porque no se sabe la tonada" and I think that’s beautiful.
@Migueldeicaza I can make it as far as “they don’t ____ because they don’t know the tune,” which is kind of delightful on its own 😂
@steve in Mexico, donkeys are associated with stupid. People say “that guy is a donkey” which he is dumb. And the name of the noise donkeys make is “rebuzno” :-)

@Migueldeicaza @steve

In Spain donkeys have exactly the same reputation, but I never heard that phrase.

We have another one, especially offensive: "más tonto y no nace". Related: "eso no se le ocurre ni al que asó la mantequilla".

O también: Llega a salir un poco más tonto y lo tendrían que regar. 😁
