A snarky put-down that needs to do a double take

I came across a sentence, "A modest man but then he has so much to be modest about (他是一個謙卑的人，但他還有很多卑微之處)" regarded as a "high-class" put-down attributed to Winston Churchill. Churchill used this sentence to deride his political rival in which many people may need to do a double-take before understanding its true meaning. Political dogfight does not need to be in-your-face; rather, a more euphemistic way as in this sentence may have the same effect.
