I don ' t think thin is the adjective I ' d use , but I guess compared to ranch dressing , yeah . Thin . <| sep |> I don ' t know much about the techniques used in filming comedy . But I know enough to recognize how brilliant this is . It ' s so simple yet effective . The slow zoom in , the music , and Charlie ' s performance all build tension . Then , when Dennis suddenly blurts out his outrage , the camera zooms out , the music stops , and Charlie goes , Hm ? None of these things are complicated , yet the result is really funny . I ' ve watched this episode and seen this clip maybe a dozen times , and I still chuckle whenever I watch it . The It ' s Always Sunny gang use every tool at their disposal to make a hilarious show . The writing is topnotch the performances are great they give everyone the opportunity to improv without relying too heavily on it even the camera work and the sound design contribute to the comedy .
