When House and Wilson are chatting in the bar, after Wilson breaks the window with the bottle, the sandwich in House's hands changes between shots. First time, its right edge is towards House;s right; next shot, it's bitten on both sides and then alternates.
In one scene when House and Wilson are in the car on the highway/freeway; the camera zooms in on the rear view mirror, in which you can see the police slowing traffic for filming.
