About this sound
This is a short Portuguese voice clip built around the line “Caramba, isso é tão errado,” spoken as Capitão Cueca reacts to something clearly out of place, lasting about three seconds. It gives a funny, awkward feeling of disbelief, as if the speaker has just caught something that should never have happened.
