The line comes from the Portuguese language dub of Shrek, the DreamWorks animated franchise that began in 2001 and made Donkey one of its most quoted characters. In Portuguese burros means donkeys, so the phrase plays directly on Donkey's role and on the everyday use of burro as an insult for a foolish person. Short dubbed film lines like this spread widely on Brazilian and Portuguese soundboards and in meme edits, where the familiar movie voice makes an ordinary insult instantly recognisable even out of context.
About this sound
Short Shrek clip in Portuguese saying talvez não funcione com burros, used as a funny reaction when a plan fails or someone acts foolish online.
This is a brief Portuguese dubbed line from Shrek built around a deadpan putdown aimed at donkeys. A character delivers the phrase talvez não funcione com burros in a calm, matter of fact tone, as if explaining an obvious limitation. The joke lands because the wording sounds reasonable while the insult is blunt, especially for anyone who knows Donkey as the film's talkative sidekick. At just over two seconds it cuts in cleanly, leaves a short beat for the meaning to register, and works as a dry, sarcastic sting rather than a loud punchline.
