It was about a kid whose mother was married to, or dating John Lithgow, IIRC, and he decided to build a nuclear bomb for his science project and used Lithgow's access as an employee of the facility to break in. There was also a remote-control car involved in the plot, and I remember his line to the love interest that he learned to pick locks from the CIA - "childhood improvement association" which I believed might be a real program or school or something for about a week until my efforts at attempting to locate and enroll failed, and I asked my mother about it, and she explained the joke to me. I was not amused. I REALLY wanted to learn the skill set that I presumed was responsible for the kid being able to break into a nuclear facility and construct a nuclear weapon. I may have been a very troublesome child to raise in hindsight.
