In a double-length special, GrandPat objects to the family selling his items at a yard sale, detailing the various memories they hold for him.
The Yard Sale contains examples of:
- Added Alliterative Appeal: Princess Pearlina's letter to GrandPat: "I've got a malignant mandible molar that's in need of your marvelous medical magic!"
- Breaking the Fourth Wall: After GrandPat's first flashback:Patrick: So? Tell me about ancient Rome!
GrandPat: Oh, I just did! Didn't you see the flashback?
Patrick: Oh. I must have dozed off. - Canis Latinicus: In Roman times, a spectator at the Clamiseum is seen chiseling the words "Weus Lovus Moronicus" into stone.
- Captain Obvious: GrandPat's description of the future.GrandPat: Everyone in the future is older than they are now! Even you will be a geezer in the future!
- Cassandra Truth: A young girl tries to buy a hula-hoop from GrandPat, but he insists it's an "oldie-o", a robotic device from the future made to instantly take care of old people. The girl repeatedly argues against him, and ends up getting it... only for it to turn out that GrandPat was right.
- Circling Birdies: In GrandPat's Roman flashback, Moronicus accidentally smashes headfirst into a column, and three images of people riding chariots circle around his head.
- Electronic Speech Impediment: The robot that gives GrandPat his oldie-o stutters while saying the word "geezer".
- Flashback Effects: When GrandPat starts having a flashback, crude scribbles fill the screen over a Fade to White, then it fades into the flashback.
- Flashback Stares: Exaggerated. GrandPat's eyes go blank white as he tells a flashback; sometimes, he has beams coming from his eyes that project it.
- Garage Sale: The present-day setting of the episode. The family is trying to sell GrandPat's "old junk", but they're all actually from the various jobs he's had across history. Instead of letting people buy them, GrandPat just offers them a lollipop — most of them accept. At the end of the episode, GrandPat himself is sold, by a family who needs a new grandfather.
- Mondegreen Gag: A visual example. As a traveling salesman, GrandPat finds a door that says "Go Away or Else!" He misreads it as "Go Away, Elsie!"GrandPat: Good thing my name ain't Elsie! [knocks on door]
- Old-Timey Cinema Countdown: When GrandPat projects a vision of his flashback, it starts with an old-timey grayscale countdown and cuts out at two.
- Real After All: While it's reasonable to assume at first that GrandPat is just senile or making stuff up, it's shown that his stories did actually happen. For example, his "oldie-o" from the future still exists in the present day, and he still owns the vacuum and dragon's tooth furniture from his past.
- Riddle for the Ages: If it wasn't Patrick's or GrandPat's, whose brain did Slappy buy?
- Running Gag: GrandPat repeatedly selling people lollipops instead of the stuff he owns.
- Vignette Episode: Most of the episode consists of GrandPat's four stories about history: being a carnival clown in ancient Rome, a dentist in the Middle Ages, a traveling vacuum salesman in the Old West, and returning to his clown job in the far future. Not all of the vignettes are of equal length; for instance, the third one is only two minutes.
- Writing Around Trademarks: A hula hoop is called a "loopy-hoop", because the name "hula hoop" is trademarked.
