Batman VS Iron Man (DC VS Marvel) - S4-E10
Trivia: The car that Batman slides over when avoiding Iron Man's blasts is the same car from the mini game in Street Fighter II, where players would beat up the car and tear it apart as fast as possible for more points. (00:04:43)
Trivia: The Doctor comes to Nevada in search of "A bowl of chili. The sort you only ever got in an American diner before 1962." During the 1960s, Chasen's Restaurant in Hollywood made a chili that became highly sought-after by celebrities (Elizabeth Taylor had some flown to Rome when she was making "Cleopatra."). Diners started changing their chili recipes in attempts to duplicate Chasen's secret recipe. This is why The Doctor had to go back to the 1950s in search of a bowl of old-fashioned American chili. (00:01:30)
Trivia: Dio in this episode drinks Cronenberg Whisky, just like in the manga. The fictional brand is most likely a homage to the director David Cronenberg, especially given the bit of 'body horror' appearing in this arc.
If This Be... M.O.D.O.K.! - S1-E1
Trivia: When M.O.D.O.K. and Austin are out on town, the places they visit make references to several other Marvel characters. The dragon that is serving them in the restaurant is Fin Fang Foom. The concert they are next shown to be attending is advertising Lila Cheney, who in the comics is a mutant who can teleport over interstellar distances. Lastly, the arcade belongs to Arcade, who is primarily an enemy of the X-Men. (00:10:27 - 00:10:58)
Through the Rabbit Hole - S2-E1
Trivia: The boy's comment, "Everybody is kung fu fighting" at the ruined school dance, refers to Carl Douglas' song of the same name from 1974, two years before this episode takes place, following the fledging martial arts craze in America. This song has recently (in a slight variation) resurfaced in Kung Fu Panda.
The Scorn of the Star Sapphire! - S3-E5
Trivia: After freeing Miss Taylor from the grip of Star Sapphire, Green Lantern encases her in a green energy box and flies her away. The box is shaped almost exactly like a shuttle craft from Star Trek. (00:15:50)
The Crab with the Golden Claws: Part 1 - S1-E1
Trivia: When Kuraki attempts to put the letter in Tintin's mail box before getting ambushed, the mailbox next to Tintin's is labelled Herge, the creator of Tintin. (00:05:40)
Trivia: Even though Paul Lynde was the voice of the Hooded Claw, his name did not appear in the closing credits throughout the series.
Trivia: Throughout the whole series, Oggy's house contains various disproportional rooms inside of it. For example, the living room inside of the house is literally twice the size of the house alone. What's hilarious is that Oggy used the living room only to watch TV.
Trivia: The paint job of the Zhu Li is reminiscent to the way ships were painted in WWI. The Americans and the British did this because they thought it would make it more difficult for the Germans to estimate their speed and heading.
Trivia: Elise's parents, Don and Elise Sr. Are played by Michael Gross and Meredith Baxter. Gross and Baxter played husband and wife in the TV show "Family Ties" where Meredith Baxter played a character named Elyse.
Trivia: The season one episodes "Doomed" and "Fantastic Fortitude" crossed over with the Fantastic Four series that was airing around the same time.
The Big Question / The Big Answer - S3-E11
Trivia: At one point in this episode, Hefer says "please put me down Mr. Crabs." Most of the crew from this show went on to make SpongeBob SquarePants a few years after Rocko ended, which has a character named Mr. Crabs.
Pink Arcade / Life With Feather (pilot) / Pink S.W.A.T. - S1-E2
Trivia: Pink Arcade: When the Pink Panther carries the bowling bowl to the table, look behind him and you can see the back glasses of two pinball machines spell out the name "Yakutis" - a reference to the long-time DePatie-Freleng layout artist and story man Tom Yakutis.
