Airdate: November 25th, 1993
Opening Line: "Here's The Show's Name-y"- Dot
Tower Escape: They pop up through a manhole cover
Video Review: In this homage to the classic cartoon Book Revue, Yakko, Wakko, and Dot are in a video store where the titles come to life. They have to fight off the giant T-Rex from Jurassic Park

Wheel Of Morality- Win a Free Trip To Tahiti
We're So Sad We've No More Time Together- Parody of the closing song from Carol Burnett
Video Review contains examples of:
- The Cameo: Bugs Bunny, Daffy Duck, and Baby Plucky appear.
- Genre Throwback: To the "books come to life" cartoons of the 1930s, only with VHS cassettes.
- Hurricane of Puns: The titular song is made up of this, doing wordplay on film titles.
- Muppet Cameo: One of the videos is A Muppet Family Christmas, with Kermit and Piggy on the cover. They're both pretty off-model, though.
- Produce Pelting: The Warners throw tomatoes from the cover of Fried Green Tomatoes at the T. rex.
- Reference Overdosed: It takes place in a VHS store, what do you expect?
- Rhyming List: The last verse of the first part of the titular song essentially names all of the great film actors and directors.
- Saw Star Wars 27 Times: The opening lines of the song has the Warners claim they've seen every film almost a thousand times, "and that's why our brains don't work anymore!"
- Take That!:
- Dot says that neither of the Gabor sisters could act.
- The Warners drop "bombs" at the T. rex — as in, movies such as Ishtar, Howard the Duck, and Dune.
- Tempting Fate: When they think that they've escaped the T. rex, Yakko tells his siblings, "I guess we showed him!" Then the T. rex shows up again and roars.
- Whole-Plot Reference: Very similar to Book Revue, except with VHS covers as opposed to books.
When Mice Ruled the Earth contains examples of:
- All Cavemen Were Neanderthals: The cavemen the mice encounter in 1 million BC have big brows and heavy builds. Brain calls one a "future Neanderthal", due to his expectations that mice will rule over humans.
- Are You Pondering What I'm Pondering?: "I think so, Brain, but culottes tend to ride up so."
- Cruel Elephant: Brain gets attacked by a woolly mammoth.
- The Discovery of Fire: Pinky and the Brain succeed in teaching mice to make fire before humans can.
- Elephants Are Scared of Mice: Exploited by Pinky to scare off a woolly mammoth that was about to stomp on Brain.
- Me's a Crowd: When the Brain succeeds in making mice the dominant species, he discovers that the mice that now dominate the earth are all clones of Pinky and decides to go back in time and fix everything. Sure, it'd be easy to rule over mice like THEM, but he doesn't want to.
- Mouse World: Brain succeeds in creating a future where mice are the dominant species, so everything is mouse scale when they return.
- No Good Deed Goes Unpunished: Pinky scares off the woolly mammoth that's about to crush Brain, who tells him that the mammoth was the only thing keeping a saber-toothed cat at bay.
- Pyrrhic Victory: Pinky and the Brain succeed in making mice become the dominant race by teaching them how to make fire. Too bad said mice turn out to be exact copies of Pinky.
- Rimshot: When Pinky and the Brain reach the dawn of time.Pinky: (yawns) Wake me at the "noon of time".
(stock footage of Wakko doing the rimshot from "Taming of the Screwy")
Pinky: What was that?! - Rump Roast: Brain's tail catches fire when Pinky creates fire. Brain runs into a lake to douse the fire.
Closing Tower Gag: "Chaio, America!"- Yakko, Wakko and Dot
