Porta dos Fundos is a Brazilian comedy group and YouTube channel founded in 2012, known for short, sharply written sketches performed by a rotating ensemble cast. Their productions use a brief opening vignette to brand each video, and this recording captures that sting with its closing pio sound. As the channel grew into one of the most watched comedy outlets in Brazil and moved into television and film, the intro became widely recognised by Portuguese speaking audiences and began circulating separately as a reusable transition and nostalgic reference in edits.
