A study in the Washington Post says that women have better verbal skills than men. I just want to say to the authors of that study: 'Duh.

O’Brien’s joke hinges on a reversal: a newspaper study claims women outperform men verbally, and he responds with the blunt, slangy “Duh,” implying the finding is obvious. The humor comes from the mock address to the “authors of that study,” as if a serious academic conclusion deserves only an eye-roll. It also plays on a familiar cultural stereotype—women as more verbally adept—while letting the punchline embody the very lack of verbal sophistication it teases. The line is typical of late-night monologue comedy: it compresses social commentary into a quick, self-undercutting one-liner that invites laughter without mounting a sustained argument.
