Fred leaves the annual company picnic to climb a hill with Dino. However, the exercise makes him very tired and he falls asleep to dream about the future.
After nearly demolishing a supermarket while trying to ride a skate-bone, a bored and irritable Fred is a nuisance at the Slate Company picnic, alienating his friends and co-workers, before he decides to wander away to a quiet place with Dino for a nap.
Sleep Fred does, and he seems to awaken with a long, white beard, which repeatedly trips him. Dino is gone, as is everyone at the picnic site, which is now decrepit from years of neglect. Fred walks into Bedrock-proper and learns that his buddies at the Bedrock Pool Hall are either retired or deceased- and that he has slept for twenty years! Wilma is an almost senile, old woman, Barney a millionaire (with a palatial estate called Sandstone Simian), Dino a geriatric dinosaur, and Pebbles and Bamm-Bamm a loving young adult couple.
Fred is despondent at having slept his life away before he finally awakes for real near the Slate Company picnic and learns that he actually only slept for about an hour. A man reborn, he returns to the picnic and enthusiastically and amiably participates in all of the events.

- The title is a spoof of the story, Rip Van Winkle.
- Coming five years before Pebbles and Bamm-Bamm had a spin-off, The Pebbles and Bamm-Bamm Show depicting them as teenagers, this episode offered the first glimpse of a futuristic version of the twosome, here as young adults.
- Note, Bamm-Bamm's young adult version was taller than Pebbles and Fred, and had taupe-gray hair, plus his same strength.
- Barney's estate in the dream sequence, Sandstone Simian, is a spoof of the city San Simeon, California, and the mansion is possibly a parody of the Hearst Castle located there.
- In the dream sequence, Bedrock's population expanded from 2,500 to 30,000.
- A picture of a naked woman could be seen in Barney's Mansion known as Sandstone Simian. It is unknown and uncertain how it got past the censorship.
- None known.
