Visible crew/equipment: In the episode where Alice sprains her ankle, Sam comes over and gives Alice some flowers. He leaves, and Mike walks in and the camera zooms into Alice and you can see the boom mike shadow on Mike's face.

Revealing: I can't quite remember what the episode was, but one of the times that Sam comes over to visit Mr. Brady, he comes in through the back sliding "glass" door. There is no glass in the door. You can tell this because when Sam closes the door, to do so, he puts his hand through the areas where glass would be.

Revealing: The wall behind Mr. Brady's desk at work is the exact same wall in the Brady's living room.
