This is a 5.6-second spoken line by the French secret agent OSS 117, delivering a remark about les jupes, the skirts. The delivery feels smug, flirtatious and deliberately old-fashioned, landing like a suave joke that knows exactly how inappropriate it sounds today. It comes from the character's spy comedy films.
