Oliver Crangle is a fanatic who maintains records of people he believes harmful to society, calling and writing to their employers to alert them of their actions, demand their immediate firing, and threaten to involve higher authorities if they don't comply. Unsatisfied with the results of his anonymous calls and letters, he searches for a more effective way to eliminate evil from the world. He settles on the idea of shrinking the "evil" people to two feet tall. He cackles at the idea of that plan.
His acts attract the attention of the government, and Agent Hall is sent to investigate. Crangle tells him that he has finally devised a plan to shrink every "evil" person down to two feet tall at 4:00 that afternoon through sheer force of will. Hall dismisses him as a crank, recommends psychiatric help and leaves. Before departing, Crangle warns that Hall will be two feet tall but is ignored.
When 4:00 rolls around, Crangle is dismayed to find that he himself has been shrunk to two feet tall. His parrot, Peter, calls him a "nut" for his actions.
