Joker is a television quiz format adapted in Portugal for RTP1, where it is hosted by Vasco Palmeirim and built around fast general-knowledge questions with a money ladder. Each episode opens with this short intro theme, which sets a tense, competitive mood before play begins. Soundboard users have ripped TV openings like this one for years, reusing them as cold opens for their own quiz videos and reaction edits, much like other TV show stings such as the Law and Order DUN DUN or hype intros like the DJ Airhorn.
