Bartlet's Third State of the Union - S2-E13
Audio problem: During the blackout, Donna and Josh sit together. The scene begins with the camera looking out the window, panning right to reveal Donna as we hear her finish saying, "You know what I'm surprised about?". But her mouth isn't moving at all until she begins her next sentence, and it's visible when we're hearing "about". (00:36:00)
Chosen answer: A really annoying innate lack of sense. My friends and family say the same thing all the time, and I'm endlessly trying to correct them. I think people just don't know any better and (ironically) couldn't care less that they're speaking incorrectly.
