Homer starts to recall the events leading up to the scream-inducing incident: beginning when he, Lenny, and Carl were hiking in the woods and were confronted by a young Fat Tony, only to be saved by a young Moe. Upon noticing that his bar was empty, the present-day Moe arrives at the Simpsons' home and recalls that while they sat by a fire that night, they saw a near-meltdown at the Springfield Nuclear Power Plant. The next day, they went to the old quarry for a swim, and Homer jumped in, only to find that there was no water but only mud. However, Homer recalls that there was no water in the quarry because something was blocking the inlet pipe. When Homer unblocked it, he found a rotting corpse in his lap, causing him to scream so much his voice changed from puberty.
