The exact recording behind this clip is unattributed, circulating as a short user-uploaded soundboard entry rather than a known show, film, or viral video. Its appeal comes from the phrase itself: 'en vous remerciant' is a stiff, formal French sign-off, the kind heard at the end of official letters and announcements. Online, creators repurpose that stiffness as irony, dropping the line after jokes, fails, and deliberately bad advice. The contrast between the courteous wording and the unserious context keeps it in rotation as a dry punchline.
