When the thugs chase Spence and Dennis away from the race track in their car, they wind up crashing into a vending table full of stuffed toys. Part of the crash can be seen from inside the car. In the exterior shot that follows, the camera used for the interior shot can be seen in the back seat of the car.
After Dennis gets into the car Spence takes from the race track, a patrol car comes by. Spence grows nervous and backs out of his parking space before Dennis can exit the car. As Spence backs out and then switches to drive, the shadow of the camera can be seen on the ground.
