Be sure to hang in at least long enough for the unforgettable theme song, starting around the minute-and-a-half mark.
If your drugs are singing to you, you've probably already overdosed.

Subject: A sedative masquerading as a bus safety film
There are few films that can surpass or even equal the mediocrity of Special Delivery, a horrendously cumbersome safety film for schoolbus operators that fails to captivate. Instead of simply attempting to discuss the fundamentals of schoolbus safety and procedure in a concise, forthright manner, the film's creators place the necessary educational elements within a dry, unengaging story involving Mickey Miller, a recalcitrant little boy who has developed a strong distrust of the local schoolbus and its driver, Bill Marshall. It appears that Mickey has been reading far too many James Fenimore Cooper novels, as he wears a feathered headdress and continually shoots toy arrows at the schoolbus, a vehicle that he refers to as the "white man's stagecoach." Mickey is miffed when he isn't allowed to board the bus because of his age, but shortly after he reaches "age more than five," he and his older sister Millie are taken on a special bus ride by Bill in an effort to gain the young boy's respect. After a mishmash of schoolbus operation information is conveyed during the trip, Mickey alters his attitude and begins to take well to Bill. At the end of the film, however, Bill humiliates a diminutive boy who isn't allowed to ride the bus by calling him "Shorty" right in front of all of the other children. If Bill is striving to establish a rapport with his future passengers, he certainly isn't doing a good job. This lengthy production is quite a chore to watch.
It should be a crime to wear garish horn-rimmed glasses like the ones Millie sports throughout the film.
