During the 'crazy credits' Lisa hangs up the 'written by' pillow case and just drapes it over the clothes line. The words appear to be level with the clothes line but when they show the close up of the pillow case alone there is now a clothes pin holding it up and the words are considerably lower. Then when they switch back it is as it was and Lisa just pulls it down without having to remove any clothes pin.
When Haney first demonstrates the cot-o-meter to Oliver the black and white striped flag is vertically under the box. In the next close up shot of Oliver watching the timing box being activated by his laying down the flag pops up from a horizontal position to a vertical position above the box. As Oliver gets up the timing box shuts off and the flag drops again but only to a horizontal position and not the vertical position under the box where it started from.
