Macedo is an ornithologist (a scientist in the study of birds) who stumbles, literally, one day into a gloomy junk shop to discover a canary in a dilapidated cage. Amid the flotsam and jetsum on a sea of junk, he sees the canary as a ray of sunlight playing in the darkness. When he discovers other extraordinary avian properties, he immediately purchases the bird and is stricken with Canary on the Brain. "Tico-Tico no Fubá" for this episode is played by jazz pianist Carlo Penza.
