In Bree's key locker, the key to the left of Orson's Office is labeled 'Huber', but when the camera zooms in, it is shown as 'Manager'.
While Gabby and Mark are standing in front of Mark's kitchen window, Gabby closes the window blinds. After doing so, the slats in the blinds change from pointing downward to upward between camera shots, as well as the amount of light shining through them.
When Orson sits down to turn on the TV with Susan watching surreptitious from the closet in his office, the television turns on to a football game in progress. The play-by-play game announcer is heard to say that the running back is immediately hit at the 42 yard line for a loss, though the running back can plainly be seen on the screen not getting dropped for a loss.
