A nerdy teenager buys a kit from a comic book ad. It allows one to grown mushrooms for fun and profit. Charles Martin Smith is his father and, at first, makes fun of his son and his new hobby. What transpires, however, is a rant by a neighbor about the worlds going to hell and our not knowing what to do. Meanwhile, the neighborhood kids are growing these mushrooms and people are finding them irresistible. The neighbor calls, saying he is on his way to New Orleans and that he may not be "in control" much longer. This is a classic line from the old comic ads and one of Bradbury's most famous stories. It is, of course, no different than any of the cold war junk that was going on when it was written.
