"Everyone Knows Juanita" is is a song from the 2017 Disney/Pixar animated feature film, Coco. It is a song performed by Héctor, which he sings to Chicharrón in exchange for the latter giving the former the latter's guitar.
Well, everyone knows Juanita
Her eyes each a different color
Her teeth stick out and her chin goes in
And her...knuckles, they drag on the floor
Those aren't the words!
There are children present
Her hair is like a briar
She stands in a bow-legged stance
And if I weren't so ugly
She'd possibly give me a chance
- Chicharrón comments in the fact that Héctor changed the lyrics to accommodate for Miguel's presence. The word "knuckles" was most likely supposed to be "knockers", in reference to Juanita's breasts.
