The exact origin of this clip is not widely documented, so it is best understood as a Portuguese-language internet meme rather than a line from a particular film or interview. Its humour comes from naming Jet Li, a well-known martial arts film star, in an ordinary warning about lending a CD, an object that already feels nostalgic. Short clips like this travel easily between soundboards, chats and short videos, where a single recognisable phrase can stand in for a whole joke. That mix of specificity, brevity and randomness is why it keeps being reused for borrowing jokes.
