This clip is a brief 2.5 second Spanish voice line saying yo no lo conozco señor, delivered as a polite but firm denial. It feels dryly funny and a little awkward, like someone backing away from trouble while trying to stay respectful, which makes the flat delivery land as a perfect deadpan deflection.
