Continuity mistake: Will, Josh, Donna and Toby are in Josh's office talking about Toby's twins; Josh leaves the office with his arms by his side, but when the shot switches to show him coming through the doorway, he is clutching his books to his chest. There was no time for the change.

Continuity mistake: When Margaret walks into Leo's office and he sleeps, the screen says it's the sixteenth hour of Zoey's kidnapping. Leo asks Margaret what time it is and she says it's almost 5:00. At the beginning of the episode when Abby and the president talk at the residence, the president says it's 6:30, and the screen says it's the eighth hour of the kidnapping, then if we move another eight hours until we get to the sixteenth hour of the kidnapping, it would be 2:30, not 5:00.
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.
