- Too many to list individually, but they tried to get away with as many innuendos and double entendres in each episode as possible. Kevin Murphy is on record saying that basically the writers wanted both kids and adults to laugh at the same jokes, but for different reasons.
- There was a subtly dirty running gag throughout the Kaiju/Attack of the 50-Foot Whatever films, when the stock footage was deployed showing missiles ... erecting themselves, Joel and the bots would greet the sight with a chipper "Good morning!"
- The Satellite of Love is familiarly referred to as the "SOL" (a well-known acronym for Shit Outta Luck... which could also fairly describe Joel's/Mike's/Jonah's position).
- In The Crawling Eye, Joel asks the bots what they think of the movie. They start talking about human heads and what happens with them, when...Crow: I was listening to the scientists, and they said you had your head up your a--
Joel: [Covers Crow's mouth with his hands]
- In The Slime People, Servo calls 3 of the titular slime creatures "The three splooges!"
- Joel's "Nitro Burning Funny-Pipe"note from the Robot Holocaust episode...despite the verbal references to tobacco note , looks an awful lot like a bong.
- In The Hellcats, a film with a frankly alarming number of jets of beer foam flying around, Crow repeatedly remarks "I hope that's beer."
- In a host segment of Godzilla vs. Megalon, Crow and Tom were looking at some photos with great interest and hide them from Joel.
- Joel's riff from Pod People: "Trumpy felt scarred by his ugly hillbilly...nose." A reference to a notorious bit from Albert Goldman's controversial 1981 biography of Elvis Presley. note
- In The Amazing Colossal Man, when the title appears, Crow snarks, "Oh, yeah, you wish!" Then there's this line when Glenn's fiance Joyce is talking to him.Servo: (as Joyce) I'm still looking forward to our honeymoon!
- In the opening credits for Mighty JackJoel: "Sex cameraman"? Is this a—
Tom Servo: No, that's "SFX", Joel.
- In Mr. B Natural, there were a couple of them:Buzz: I'd better go up to my room and do the reading.
Mom: All right, son. (pause) Uh, Buzz?
Crow: Now, this time don't make so much noise when you "read".
Mr. B Natural: You gotta inspect your horn, boy!
- Done again later on:
Crow: And wash it every day!
- During the "Snow Thrills" short in Episode 311, we're informed by the narrator that "skiing" is properly pronounced "shee-ing". Joel retorts, "Yeah, well, you're full of skit."
- The writers oftentimes say things like "You can get away saying certain things with a puppet that you couldn't with a person". Notably Crow's "I wanna decide who lives and who dies!" line from Santa Claus Conquers the Martians.
- Joel's infamous riff in The Castle of Fu Manchu involving bicycle seat covers.
- In Gamera vs. Barugon, one of the monster shoots out a long... something from its mouth, prompting Joel to say "I'm your boyfriend now!" and make a flapping noise with his tongue.
- Joel's "Pocket Pool" Invention Exchange.
- The riffs where the police chief refers to people not wanting to "kiss his bird" in Bride of the Monster.
- The lyrics to "Tubular Boobular" exploit the fact that while certain words would be censored, nonsense words that sound just like them can slip through - provided you use about fifty of them.It's an arealogical, autoerotical, tubular boobular joy
An exposular-regional, batchical-pouchular fun for girl and boy!
A latissimal-dorsical, hung-like-a-horsical, callipyligical ball...
- Outlaw is full of butt puns throughout. And Servo and Crow about to comment on a phallic statue before Mike stops them. They still get away with "I was just going to say I envy that structure..."
- In Santa Claus, Santa has a bunch of "technologically-advanced" devices including the TeleTalker, which is a mouth on the wall that speaks things that people are saying across the globe. It looks so questionable, though, that Tom even wonders, "I hope those are lips."
- Subverted in the opening for Bloodlust, where Gypsy attempts to circumvent the censor, and accidentally invokes the word she was trying to insinuate.Gypsy: [Regarding Pearl] Boy, I'm tempted to call her something that rhymes with "bitch" — Oh! I said it!
Bots: She said it! Gypsy's in trouble, Gypsy's in trouble!
Tom: [Later, in the theater] Can I say it?
Mike: No, you can't say it.
- In the short Why Study Industrial Arts, a quick shot of a construction worker hammering at an unidentified object between his legs inspires the riff: "I can't get this thing back in my pants, Earl!"
- During a segment of The Starfighters, during the "refueling scene", Crow sticks his beak up Servo's hoverskirt. Servo gasps for a moment, then clearly enjoys it.
- Perhaps the dirtiest riff they ever made was during the short "Out of This World" (which aired before the feature High School Big Shot), in which a protagonist sticks her tongue out at the antagonist; Tom's response is, "No, thanks; I use toilet paper!"
- In Deathstalker and the Warriors from Hell, there's a guy with their sticky mucus-like food in his beard and a dopey grin on his face. Servo's quip: "Guess what I've been doing!"
- Since Once Upon a Honeymoon is about a songwriter forced to work before leaving on his honeymoon, the short is filled with these.Crow: Let's see... What rhymes with "blue balls?"
Mike: What would Liberace do?... Oh, I better not do that.
- Laserblast has an instance not from the riff, but from the film itself. One of the cops says "shit" at one point near the beginning of the film, and despite the volume being lowered in an attempt to mute it out for the show, the word can still be made out.
- When Tom Servo blocks the hull breach with his hoverskirt, he starts giggling uncontrollably as the vacuum of space sucks at him from underneath, declaring, "I'm experiencing a sensation altogether new to me, and frankly, I love it!" When Mike removes him, he growls, "Aw, darn."
- The riffs during a scene involving runaway truck rigs on a hill in Riding With Death, non-stop sexual double-entendres that get more blatant and dirtier with each riff ("Mah rigid grill structure is bearing down on yer unprotected cargo door."), culminating in Crow's line, "My oft-complimented Peterbilt is rhythmically nudging that sweet honey pot of yours—" which leads Mike to put the kibosh on the whole thing.
Mike: "Drained and satisfied, I'm tracin' lazy circles on yer supercab now..."
- Which of course, leads to this:
Crow: And you said I was bad.
Mike: Well, you inspired me.
- Along with the above, Servo shouts "She's PREGNANT?!" after the main heroine announces she's late.
- When Mike gets frustrated with Bobo's antics as his defense lawyer, he starts throttling him. Later, Crow asks why Mike was choking the monkey.
- Kevin Murphy's ancient-Roman character whom the Pearl-era Mads accidentally drop in on is named Callipygeas. This isn't a Latin name, it's Greek — and it means "one who has a nice arse".
- Before Invasion of the Neptune Men, Pearl is heckled by a Roman citizen because of her lack of popularity in comparison to Bobo, to which Pearl quickly replies, "Slut? I mean, what?"
- Space Mutiny starts with this and rapidly ascends to Refuge in Audacity.
- The Projected Man has a truly volatile one: the lead female actress says "You can't, Chris!" and Servo remarks, "What'd she call him?!" Say her quote aloud to yourself in a thick British accent to get the joke.
- Not to mention a direct mention of the Kama Sutra after a detective states that he's seen a dead acquaintance "in a great number of positions before, but nothing quite like this!"
- The crew doesn't even try to hide their fixation with Thena's breasts in Quest of the Delta Knights. To be fair, neither does the movie.
- Hobgoblins has this quick (but incredibly dirty) zinger in regarding the rather... effeminate Club Scum emcee:Emcee: Oh, I'm sorry, the mud wrestlers are supposed to use the back entrance....
Mike: Well, you'd be the expert on that...
- Squirm has this exchange:Geri's mother: I just don't want you to be disappointed if he doesn't come.
Crow (as Geri): Mother, that's private.
- Jonah states if he's given a space suit he'll need one with more room in the "groinological area". From the bots reaction, it's pretty clear what he's implying and it's not about his height.
- In Yongary, a newlywed couple is called into work just as they were about to go to bed. The wife gives the phone's antenna a frustrated shove back in, and Jonah makes fully explicit what was likely intended as a Visual Pun even in the film itself: "That's a metaphor for our honeymoon."
- In Wizards of the Lost Kingdom II Jonah and the bots are reading an emoji version of Lady Chatterley's Lover:Jonah: Oh, that's a lot of eggplant emojis...
- In Carnival Magic when the film gives us an awkward shot of Alex the Chimp with one of the female human characters standing over him, Jonah brings attention to how it could misinterpreted.Jonah: Oh, she's just giving him a belly rub.
