Non-sexual example: when Terra reappears in Teen Titans, her first line is "So... which team am I on?" She's referring to volleyball, but it alludes to her becoming the Sixth Ranger Traitor.
The Ambiguously Gay Duo from Saturday Night Live is based on these, from the episode titles (such as "A Hard One to Swallow" and "First Served, First Come") to the dialog to their car. And the plethora of Sight gags in each episode, lampshaded by "...what's everybody looking at?" "Nothing!"
In "Hercule Yakko", Yakko takes the role of detective on board a ship. Instructing his sister Dot to check for prints, she soon returns with the singer Prince in her arms. Yakko clarifies it as "fingerprints", wiggling his fingers. Dot merely glances at Prince, who leers at her, and remarks, "I don't think so."
One episode, "Hot, Bothered And Bedeviled" is about the gang trying to find "Six Flags Over Flushing". This might mean that Wakko is having a Potty Emergency.
Wilt:[referring to a vacuum cleaner] No, Ed, no! Not blowing! The other way! The other way! Eduardo: Other way? [flips switch] Wilt: Yeah, yeah! That's really sucking! Eduardo:[sighing] There's no pleasing him.'''
Bloo:[watching a golf show] Look! That man's hitting a little white ball into a hole!
South Park: For a number of episodes, the main characters got a new teacher whose name was Ms. Choksondik (pronounced "Chokes-on-Dick"). Humorously, none of the otherwise dirty-minded main characters seem to have understood the joke, and have made fun of her by calling her things like "Ms. Choksonrocks" or "Ms. Makes-me-sick".
The Movie was also called South Park: Bigger, Longer, and Uncut. If you don't get the entendre there, think about it for a while.
The title is also a Shout-Out to 15-Minutes-of-Fame John Bobbit's porn movie.
What makes this even better is that the original subtitle was "All Hell Breaks Loose", but the "Hell" in that was unacceptable, unlike the final title.
Also, Chef's songs and his chocolate salty balls.
As long as we're talking about songs from South Park that have double entendres, how about the ones that aren't sung by Chef? Like the "Getting Gay with Kids" song from season three's "Rainforest Schmainforest" episode? Or that song Butters tapped to in season eight's "You Got F'ed in the A"?
In AWESOM-O when Butters receives a huge box as gift, he cheerfully babbles what a big package it is and how he always wanted to have a big package.
Rocko's Modern Life was famous for the sheer amount of (very thinly veiled) double entendres it has employed. Some examples include the Show Within a Show "All Scottish Show" (as an acrostic), a fast food restaurant called The Chokey Chicken, a board game the characters play called Spank the Monkey, an eye doctor cupping one of Rocko's eyes in his hand and asking him to "cough, please", a ride operator at a carnival reading a magazine called "Playslug", immigrants from a country called "Balzac", a toy for dogs called "the Doggy-Style rides", and a banjo-playing coon saying menacingly "We're gonna make you squeal, piggy!" (He then proceeds to pull a pig from behind his back and tickle it with a feather, making it, in fact, squeal). All this from a show intended for elementary school children.
The Simpsons episode "Whacking Day" is about an annual Springfield tradition to bludgeon snakes to death with clubs. Lisa Simpson is horrified by this barbaric tradition and brings Barry White to lure the snakes away from being whacked as they are attracted to his sensuous music. Are you picking up the subtle innuendo here?
Danny Phantom is known for innocent lines of dialogue that could mean something... else. For example:
Danny: I couldn't sleep with my arch enemy in the guest room next to me. Sam: My parents sleep in the bedroom next to me. It's not the same, but I can't sleep, either. (and) Sam: You'd scream, too, if you were stuck in a sleepover with [Paulina]. Danny: Actually, I kinda doubt that.
Sam:(dancing with Danny) Promise me you'll keep your pants up? (Danny's ghost powers had unintentionally made them fall down in front of Paulina) Danny: I'll do my best!
Also, watch the episode "Eye for an Eye" and just hear any insults between Vlad and Danny. Their words have a very Subtext feel to it and they say it so frequently it just borders on Foe Yay.
Season Three in general is rife with Danny/Vlad Foe Yay and subtext. It's all over the place.
Maddie:(trying to remove the bottom half of a deadly battle suit) Vlad, help me get these pants off Jack! Vlad: Nope. Sorry. That's all you.
Beavis And Butthead have a special talent for finding double entendres in the most innocuous of statements — even if they have to isolate specific syllables within a word in order to do so, and if the double entendre makes absolutely no sense or has absolutely no relevance to what's going on at all. And yet they sometimes fail to understand plainly spoken or shown sexual references, when that works better.
Van Driessen: ... There's a wonderful world out there when we find we don't need TV to entertain us. Butt-Head:Huh huh huh. He said "anus".
In the episode The Enchiridion, Princess Bubblegum tells everyone to turn around while she shows Finn her "secret place".
There's an episode featuring a talking heart named Ricardio who, when introduced, was giving Princess Lumpy a "special massage meant only for best friends" and assured everyone that it was "completely consensual".
There's one case where, when trying to distract Jake, Finn tells him to play "fifteen minutes in heaven" with his girlfriend, and shoves them in a closet. To top it off, there's an episode where Jake is so attractive he's causing animals to rush to him-including snakes. Finn then says "These snakes are everywhere. There's even one in my underwear!" as he holds up a pair of underpants with a snake in them.
When Finn and Jake pull Billy's sword, one exclaims that it's Billy's "legendary crack".
In the first episode where Finn and Marceline hang out, Finn mistakes Marceline's gig as entertainer for the Nut Kingdom as an undead invasion and brings about this piece from the Duke of Nuts himself: "But why would someone want to sack my nut castle?"
In the TV cartoon The Flintstones, Wilma is pregnant, and needs to be taken to the hospital. Her husband Fred's best friend Barney follows along to help Fred get her into the hospital. Barney is, however, too aggressive moving her out of the car, and as a result, spins the revolving door so fast Fred is spun out, and across the street into a hotel. Arriving at the front desk, Fred, quite calmly states the truth, "I'm looking for my wife, she just came in here with my best friend." The clerk, nonplussed, simply says, "Look, we don't want any trouble here", to which Fred responds, "What kind of a hospital is this?" to which the clerk replies, "This is a hotel; the hospital is across the street."
There's also the Season 5 episode "Ancient History" where Hawkman and Hawkgirl battle the Shadow Thief. At one point Hawkgirl attacks the Shadow Thief with a whip, and Hawkman, who believes the two are reincarnated lovers, says:
Hawkman: You always were good with that thing.
Then there's the episode where reporter Linda Park (Flash's eventual wife in the comics) attempts to explain to a friend why she finds Flash attractive:
Linda: Gosh, he's a total babe! Like the entire track team at once! Um...
Explaining how she established project Batman Beyond:
Amanda Waller: Bruce's DNA was easy enough to obtain: he left it all over town. (Terry reacts with an Eye Take). Not remotely what I meant.
Harvey: So as we see from this tape your power was... Apache Chief: Growing large, at will... especially in the mornings.
The scene usually cuts to Judge Mightor waving objects like a golf club or a pool noodle saying "Deedle leedle leedle leedle." whenever a phallic related double entendre is made.
Secret Squirrel is convicted of flashing:
Mentok: Looks like the squirrel's been showing everyone where he keeps his nuts.
Harvey's closing arguments for that episode were loaded with them, which Mentok dutifully lampshades.
Harvey: Every time this squirrel opened his coat, it was to pull out a critical tool— Mentok: I'll say!
Phil Ken Sebben is always firing off a load of these. Ha ha! Load!
Ed, Edd n Eddy occasionally dabbles in this. Like in the episode "Run For Your Ed", where Rolf is seen carting away a giant sausage and boasting "Rolf's giant wiener will fetch a pretty penny at the market".
The Looney Tunes Speedy Gonzales shorts feature a few of these, when the mice need to get Speedy's help and someone knows how to contact him...
Mouse 1: Sure! He friend of my sister! Mouse 2: Speedy Gonzales friend of eeeeeeeeverybody's sister...
Everything Black Cat says. I distinctly remember a line about Spider-Man getting his goop in her hair.
Possibly unintentional, but MJ says this to Peter and Gwen in the New Year's Eve episode:
MJ: You [two] could go down to Times Square, watch the ball drop. (winks)
One interesting stretch of dialogue in Code Lyoko takes place between Ulrich and Odd as they're getting out of the shower (common bathroom at a boarding school, in case you're wondering), with Odd talking about Heidi, the last girl in his class he hasn't dated:
Odd: Hey, speaking of "hot chocolate", I finally got a date with Heidi. Ulrich: Eh, you gonna give her your croissant?
The writers were playing with the "croissant" jokes throughout the episode, but there was absolutely no way the hidden meaning of the last one was that well hidden.
Family Guy will usually do the old joke of a string of double entendres, followed by a plain-spoken line that makes it clearer than it ever had to be they weren't accidents. When they don't do this, the double entendres are borderline single anyway. In one episode, specifically about Peter's (heh heh) jealousy of Chris' enormous... Little Chris, he tries several stereotypical methods of compensating, most blatantly a red car with an unreasonably long and phallic hood. He then drives at an overpass saying, "Don't worry, baby, I'll be gentle", stops halfway through, reverses, goes forward again, and repeats. Then he's met headlong by another vehicle, making his car as short as a Volkswagen. Then a bus drives by full of beautiful women pointing and giggling.
Brian: So, uh, where's your good buddy James Woods? Peter: Eh, turns out he wasn't so good at catching stuff in his mouth. So where's your girlfriend? Brian: Same problem. Brian & Peter: Wooooaahh!!
When Stewie wants to follow Lois on a cruise:
Stewie:Farewell, Brian, I'm off to sea. An hour from now, I'll be surrounded by seamen; sperm whales and seamen. Oooh, a swallow.
Subverted in one episode when Quagmire actually runs out of innuendo.
Quagmire: You know what I'm talking about right? (silence) Oh!
Peter: I am gonna sue that bastard and make him pay out the ass. No ifs, ands or but(t)s. I'm gonna be real anal about this. ........... Sphincter!
Peter: Just don't forget our deal, Lois. I sit through this and later tonight I get anal. You hear me? No matter how neat I want the house you have to clean it.
In the episode "Jerome Is the New Black", when Peter finds out that Lois used to date his new friend, Jerome:
Peter: Well, you datin' that guy? It's just a lot to take in. Lois: Oh, you tellin' me!
Later in the episode Peter becomes very insecure, causing Lois to proclaim, "Come on Peter, it was over ten inches ago! I mean years!"
Or in "Quagmire's Dad", where Quagmire is stressing about the possibility that his dad might be gay...at a reception held by his fellow navymen in his honor:
"Glenn, you should be very proud of your dad. It was an honor to serve with him. Come on Dan, let's get a drink. So glad to see you back in your element, surrounded by seamen." "Your dad took supplies where no one else would go! I can't tell you how many loads your dad took when I served with him!" "Everyone here admires your dad. He'd walk into an army barracks and make every private feel special. He really knew how to stroke those privates." "Your dad was the cock of the walk, Glenn." "Every day at rifle training, he'd help me clean my butt!" "Your dad once drank me under the table!" "If there was one man you wanted in your hole, it was your dad!" "Your dad had the best penis in the military!"
(after Quagmire finally freaks out and runs to his dad)
"Glenn, you're ruining this ball. You know how much I love balls!"
And then there's Quagmire's face, shaped kinda like... well, with his nose and chin it's kinda obvious.
The Drill is about stopping a giant drill from penetrating the wall of Ba Sing Se and releasing soldiers to conquer the city. However, Katara and Toph manage to increase the pressure on the drill from behind, so that some sludge spews out◊ prematurely. Then Aang works the front and causes it to explode◊.
The Fire Nation intends to penetrate the walls of Ba Sing Se (which proudly translates to "inpenetrable city") via use of a mobile drill tank. Aang and Katara weaken the metal column supports inside the drill using waterbending in hopes that the machine would collapse on itself. When this doesn't work, Katara and Toph build up pressure by water/earthbending (respectively) the rock slurry back into the drill. Aang delivers the fatal attack to the drill by earthbending a stone pin, running up the wall of Ba Sing Se, running down the wall at super-speed, and hitting the pin with a powerful blow. The drill then collapses and the slurry system ruptures, resulting in Azula's plans being foiled yet again by "Team Avatar."
Along the same lines, in "Nightmares and Daydreams" Aang has a daydream about finally confessing his love to Katara, and when he snaps out of it she asks what he was dreaming about. He replies with:
In "Bitter Work", Toph is deliberately pissing Aang off to teach him to stand his ground like an Earthbender. She steals his bags of nuts and cracks them with his staff, which she notes "isn't the only delicate instrument around here".
Fry:(after escaping from Lrrr) Yes! I never thought I'd escape with my doodle, but I pulled it out! Bender: Just like at the movie theater! Wooooo!
The Simpsons has done this many multitudes of times over the years. However, there is one episode in particular that stands out... the episode where a sudden snowfall traps the kids in the school with Principal Skinner has lines like "Ach... that's the last time you'll slap your Willy around" (- Groundskeeper Willie)... "Good work, Nibbles. Now chew through my ball sack" (- Principal Skinner, trapped inside a duffel bag that held dodgeballs)... and a suspicious looking silo full of "salt" that explodes when it hits the ground.
Marge: You turned Springfield into America's trash hole! Homer: Marge, Ix-nay on the asshole-tray."
The "We Put the Spring in Springfield" song from "Bart After Dark" is a pretty clever one. It's the episode where Bart (and subsequently everyone else in town) finds out about that Burlesque house. So that "spring" could refer to other things...
The Legend of Zelda cartoon was remarkably full of Parental Bonus lines, although few of them were presented as double entendres. However, in the episode "A Hitch In the Works", Ganon offers a gem when he orders the abduction of Zelda. Making it even funnier is the fact that he's ordering his mooks to kidnap her so he can force her to marry him:
Ganon:I want that princess!
In episode two of Static Shock, Virgil is talking to his doctor, trying to figure out if the Bang Baby gas he breathed in will have any adverse affects aside from his superpowers. He does this while not telling the doctor that he inhaled Bang Baby gas. It sounds like he's talking to the doctor about puberty and being sexually active until Virgil realizes that's what it sounds like.
Archer: You said no dates! Malory: I said no such thing. Archer: Well, your mouth did! Malory: Well, your mouth better get over there and make Torvald happy! Archer: Um, phrasing? Malory: Regale him with exciting tales of ISIS exploits!
Larkin:(to Ingrid) Hey, Third! How'd you like that cream pie?
Probably unintentional but in an episode of Rugrats in which Chuckie becomes obsessed with Tommy's Mr. Boppo toy (a clown punching bag) and isn't paying attention to his friends Phil remarks "A kid should be outside playing with his friends not bopping his Boppo all day".
Vanessa: Well, Ferb, you sure know how to show a girl a good time. Doofenshmirtz: I had to disable it. It was doing weird things to my head, man.
Complete with a stoner-like accent.
Candace: Hmmm... maybe they should call it jump, duck and blow! Jeremy: At least you don't have a weenie on your head! Major Monogram: Carl, don't forget to lift the seat when you're done! Norm: I'm drilling! Background Singer: She's gonna be a big sensation, cuz she's sporting major kinkification! Candace: ...and I am NOT using the banana this time!
Candace: Oh, yeah, Jeremy. Nobody makes a corn dog like you. Doofenshmirtz: This is really a two-handed job. Laird Hamilton: Whoa, you got pounded! Jeremy: Y'know, Candace, I've had a lot of fun in your backyard, but this is the best time yet. Candace: Oh, pardon my reach. I'm just getting in the most convenient position to drive this stake into the ground.
The animated Beetlejuice: In "Mom's Best Friend", Beetlejuice changes into a dog and can't change back because of a restrictive collar around his neck. Sweet, innocent little Lydia delivers this as she takes out a pair of scissors:
Lydia: I know how we'll fix it...we'll cut it off! (Beetlejuice shrieks in panic; Lydia shakes her head long-suffering)
Grim puts a powerful artifact in his mystic trunk and warns Billy to "Stay out of the junk in me trunk!"
In the Aqua Teen Hunger Force episode "Revenge of the Mooninites", the Mooninites are watching porn stolen from Carl's secret stash, leading to this exchange:
Meatwad: Ooh yeah, baby. That's a neat car she's washing. You think that's a straight six? Err: I think I have a 'straight six'. Ignignokt: Ooh, Err, your sexual innuendo is priceless.
King of the Hill had it in the episode "Texas Skillsaw Massacre," where Hank and Dale were arguing after Dale came out from having his finger re-attached. Bear in mind that the medical personal thought it was a domestic dispute between the two of them, and then Dale says
From title to conclusion, The Powerpuff Girls episode "Members Only" is loaded with double entendres.
The show manages to pull off a rare quadruple entendre in naming a villain Dick Hardly.
A non-sexual example occurs in The Critic, where Duke Phillips is on hold with the "spastic colon people". He asks if they can hold. Naturally, they can't.
Another non-sexual example occurs at the end of the two-part premiere of Batman Beyond. Bruce Wayne offers Terry McGinnis a job, and tells him, "Welcome to my world." when he accepts. Terry's mother thinks he's referring to the world of the wealthy and powerful; Bruce and Terry (and the viewer) know that he's referring to Terry taking up the mantle of Batman.
