A timestamped CCTV frame of someone caught restocking at 2am — surveillance deadpan that sells the craving as evidence.
Vertical 4:5 frame recreating the found-surveillance-footage technique: a real CCTV still whose joke is deadpan absurdity in a mundane place. High corner-mounted camera view of a bland office elevator lobby — brushed-steel elevator doors, pale tile floor, fluorescent flatness — washed in desaturated grey-blue with soft motion blur, mild wide-angle distortion and visible video noise. The elevator doors stand open, and stepping out mid-stride is a person in full snorkeling kit — mask, snorkel, swim fins slapping the tile — otherwise dressed for the office, carrying [PRODUCT — e.g. "a shrink-wrapped six-pack of Sazzo citrus electrolyte water"] under one arm, labels facing camera and legible through the blur. The edge of an unbothered colleague's shoulder exits frame left. Overlay authentic surveillance graphics in small white pixel type, top left: [CAM LABEL — e.g. "07(B) LOBBY EAST"] with the timecode beneath: [TIMECODE — e.g. "08:11:26"]. Nothing else — no captions, no headline; the credibility of the artifact is the whole gag. Bottom right, one tiny semi-transparent logotype: [BRAND — e.g. "SAZZO"]. Keep the comedy warm and harmless. No menace, no weapons, no night-vision green, no clean studio light, no real security-system names, no watermark, overlay text crisp and correctly spelled.
