After Beatrice (the house cleaner) gets out of the hospital and goes to live with her mother, she has candles lit on the bureau. Her mother says that they're a "fire hazard" and blows them out; we see her bend down, blow out the four candles on the right of the mirror (accompanied with four blowing sounds) and stand up. When she stands up, we see that all six candles, including the two to the left of the mirror, are smoking; however, she never extinguished the two on the left.
The computer monitor that Troy sits behind after his promotion has neither a power nor signal cord connected to the rear panel (other, similar computers are conventionally connected).
The J & B Scotch that Troy drinks after he leaves the scene of the accident is too yellow and has a thin layer of foam on top - it looks more like ginger ale or something similar.
Walker writes the formula for acceleration incorrectly on the blackboard. It should be f/s2, where he writes (f/s)2. Then, a student says: "Don't you have to assume that the velocity is constant during the deceleration period?", and Walker partly agrees. Deceleration means that the velocity (or rather the speed) diminishes - constant velocity means there is no deceleration or acceleration. A physics teacher should never make these mistakes.
