Simply put, toilet humour comprises jokes about urine, feces (human or otherwise), bums, fannies, willies, other naughty bits, fluids, farts and the immolation of them, boogers, bodily functions, and various other yucky stuff. It is very popular with young children, but as they grow up, they tend to find greater amusement in more witty jokes (at least, most of them do), and toilet humour is generally regarded with great dislike from the eyes of the mature audience. On the other hand, when toilet humour is mixed with Slapstick, the result is generally viewed as humourous. People falling into manure is good for a laugh across all age groups.
Toilet humour is related to Vulgar Humor. You could say it is the "cleaner counterpart". e.g What did the Pirate find in the ship toilet? The Captain's Log. Taken from https://www.keeplaughingforever.com
Toilet humour is common on grossout shows and shows with large amounts of Black Comedy, but is not restricted to them. In a show which rarely relies on toilet humour, such instances tend to be lampshaded ("Oh, just what this episode needs - a fart joke"). Often toilet humour is used as filler, which results in a Bottom of the Barrel Joke.
Almost guaranteed in anything with babies in it.
Before anyone tells you humor was cleaner back in the old days, this trope is Older Than Dirt. A Sumerian proverb, dating to 1900 BCE goes "Something which has never occurred since time immemorial; a young woman did not fart in her husband's lap."
I Ate WHAT?! is the trope when eating is involved. Characters that are Gassholes and most instances of Fartillery are also usually meant for comedic purposes. Compare Tinkle in the Eye, Nose Nuggets, Road Apples, and Urine Trouble. Can be played very lightly via Calling Your Bathroom Breaks. Humor that involves an actual toilet is often involved in a Potty Emergency (but this Trope often applies there too). You can have some toilet humour without having anything gross actually happen by employing a Grossout Fakeout.

- Apparently, this commercial for baby diapers is a real Australian ad. Let's just say that the mother will be cleaning out her car for a while, and hope we never learn what a number four is...
- There are a couple of somewhat popular ads that got uploaded to YouTube and other video sharing sites countless times. For example:
- This Smart Beep ad, in which a woman farts in the car when she thinks she's alone, only to discover she was on a double date and the other couple was in the backseat.
- This Simon TV commercial where a woman pranks her boyfriend with her fart. After he gets grossed out by it, she apologizes and promises not to do it again... only to fart on him after shaking his hand.
- This ad for Jamocha's restaurant pulls a hilarious bait-and-switch.
- A campaign against secondhand smoke used the phrase "passing gas" instead of smoking in reference to the gases expelled from smoking cigarettes. The ads usually involved one character mentioning he or she needed to pass gas and the others would tell them to go to another room or do it outside as a narrator explained the dangers of "passing gas" in the presence of others.
- The "Bleachable Moments" ad campaign for Clorox had a few instances of this. In one ad, a little boy proudly informs his mother that he used the potty. The mother goes to the bathroom, looks at the training toilet, and with a confused expression says, "Where is it?" Then her gaze drifts over to a nearby vase...
- One ad that tells people to get checked for kidney disease features a song called "Everybody Pees", which is about people peeing in all sorts of crazy ways and stating that everybody pees.
- "Tinkle, tinkle, Little Claire, sitting on your potty chair..."◊
- Claude the Cat:
- If gas is mentioned, there's usually a fart joke.
- One video begins with Claude digging then saying, "So much for privacy" implying he wanted to go number two.
- In one video, Claude describes the beach as a litter box.
- Bill Cosby's famous standup act, Bill Cosby: Himself featured a rant about how fathers are the most fun family members because they're the only ones allowed to have gas. He also discussed how his father used to blame his farts on invisible animals.
- Billy Connolly's early material featured an abundance of toilet and body function jokes. The most famous example is one where he speaks at length about being trapped in an airplane toilet with the previous visitor's "jobby" still floating in it, not flushing away and being unable to leave because he'd never be able to convince anyone that he didn't do it himself! He's no stranger to jokes about willies and bums either (a joke about the latter pretty much kickstarted his career outside Scotland).
- Oh, Bob Saget. The comedy special That Ain't Right features lighting farts, an examination of the potential literal meaning of the phrase "fuck that shit", a man from Spain getting his head stuck up an elephant's ass, and that time where Bob got garlic diarrhea after eating at The Stinking Rose and then used it to kill a vampire.
- Eddie Murphy has a bit in Delirious that starts off with farting in the bath tub and ends with a turd, a cracked skull and his brother with a G.I. Joe up his butt.
- George Carlin defines a fart in its simplest context: "Shit without the mess."
- Larry the Cable Guy is notorious for overusing this.
- Gary Larson liked putting outhouse jokes into The Far Side, though he did have a problem getting them past his editors in the early years.
- One of his favorites was one featuring a boy in the foreground practicing his sousaphone behind an outhouse; in the background, beyond the outhouse, stand a cluster of awed onlookers.
- Garfield has had a few examples here and there over the years.
- Marvin...just the entire run of Marvin, a strip that seems obsessed with a diaper-wearing toddler's fecal production and his apparent willingness to sit smugly stewing in it indefinitely. (This behavior and the strip's unswerving focus on it is one of the bêtes noir of The Comics Curmudgeon.)
- BabyBlues: Frequently used as a running gag and is commonly used on Wren. Another running gag has Wren constantly eat prunes and the after-math always has her pooping herself. In one comic, Wren gets diarrhea after eating a whole bag of prunes and stinks up the van, leaving Darryl with a empty diaper bag and a trip the store to get pull-ups.
- Aachi and Ssipak has an entire plot that revolves around a future where feces is the main source of power and the main characters are protecting a hooker who has very... *ahem* generous bowels.
- Happy Heroes: Season 8 episode 11 is about Big M. being stuck floating in the air. He gets tired of not being able to control where he floats and finds a solution - propel himself in the direction he wants by farting. He then runs into an aerial traffic cop who fines him for polluting the air with his gas.
- Lavatory-Lovestory: This is a cartoon in which a lovelorn men's room attendant falls in love. In one scene all the men in the stalls are unnerved when the woman starts peeking underneath them in an effort to find her admirer. Later, she accidentally whacks a man in the face with her bouquet, causing him to fall into the toilet.
- Fully embraced by America's Most Haunted at every opportunity.
- Heavily used in Stern Pinball's Family Guy, just like its namesake. Operators can tone it down, however.
- The "Joe's Diner" mode from The Flintstones ends with a large pterodactyl flying overhead and releasing a giant dropping on the diner.

- Inappropriately enough, the South Park pinball from Sega is loaded with this.
- WhizBang Pinball's Whoa Nellie! Big Juicy Melons has a horse that's seen shooting a melon out of its posterior. Another part of the play field shows it farting onto a lit match, which launches a fireball (that doubles as a score light).
- The "13-UTT" dimension in Ric K And Morty causes fart sounds to play whenever the ball hits anything.
- The 1987 Slammy Awards: In a literal case, one of the nominees for the "Best Personal Hygiene" award was King Kong Bundy, who is seen using the toilet to defecate himself ... and it is implied he held it all in (and we mean ALL in) until his bowels finally gave way.
- John Cena occasionally pulls this out for the kids.
- Who can forget the time Eddie Guerrero gave The Big Show a tainted burrito, giving him diarrhea in the middle of a match, and then stealing all the toilet paper from the toilet stalls before he got in? And the next week, Eddie Guerrero sprayed The Big Show down with a hose connected to a septic truck.
- The Bear in the Big Blue House installment "Potty Time with Bear" pretty much operated on this when it wasn't offering practical information on children's potty training.
- On Dinosaurs, Baby often makes mention of having dirty diapers with comical reactions from Earl. Some prominent examples include the lyrics, "I take every chance to make a poop in my pants" in the "I'm the Baby (Gotta Love Me)" music video, and the entire plot of "Nature Calls" dealt with Earl's unsuccessful attempts to potty-train Baby.

Statler: No, but the guy who did had just had a bowl of my chili.
- Muppets Tonight: The Seinfeld Babies sketch from "Episode 107: Sandra Bullock" parodies the Seinfeld epsiode, "The Contest" by having Baby Jerry say that whoever can go the longest without soiling their diaper wins the contest. Baby Kramer proceeds to do his business and declares, "I'm out".
- Sesame Street: "Elmo's Potty Time" is mainly educational, but there are a few joke moments, like a giant primate needing to pee and chasing a giant toilet, jokes during a song about toilet paper being made (such as when a large toilet roll is being seen in the manufacturing process, asking, "If the roll ran out, would we hire a truck?!") and kids shouting synonyms for pee and poop, the peeing part ending in a shout of "I REALLY NEED TO URINATE!".

- The Stephanie Miller Show describes itself as "a Mensa meeting with fart jokes!"
- Martin/Molloy featured lots of this, which the hosts acknowledged and frequently mocked themselves for. The "Blimpy, the Lactose Intolerant Cat" sketches were built entirely around it.
- In 1776, at one point, RI delegate Stephen Hopkins is out using the latrine when his time to vote is called; the Congressional secretary marks this as "Rhode Island passes," sending the rest of Congress into a fit of laughter. Later, Benjamin Franklin is discussing his thoughts about not truly being an Englishman since he doesn't have the rights of one.
Franklin: But to call me one without those rights is like calling an ox a bull; he's thankful for the honor but would much rather have restored what's rightfully his.
Dickinson: When did you first notice they were missing, sir?
- The Clouds: At one point, Strepsiades is speaking to one of the students at the Thinkery, surrounded by kneeling students. When he's told that they are studying the reaches of Hell, he's quick to point out that their "third eyes" are facing the sky.

- Older Than Dirt: The oldest known joke of any kind comes from a Sumerian tablet dated to c. 1900 BCE. It's a fart joke:
- "Something which has never occurred since time immemorial - a young woman did not fart in her husband's lap."
- You...sulphurous bastard.
- Flatuists, A.K.A. professional farters, are people paid to fart on command. The earliest known flatuist was mentioned by St. Augustine of Hippo in his book, "City of God", which was written in the 5th Century A.D. One 12th-century Englishman by the name of Roland was given a feudal grant of 110 acres in Suffolk provided that every year he would, on Christmas Day, entertain the King by performing "altogether, and at once, a leap, a puff, and a fart." He and his descendants did so for 200 years.

- Leslie Nielsen's gravestone reads "Let 'er rip."
- Comedian Michael Bentine recalled his life as Intelligence Officer to an Australian bomber squadron during WW2. The Germans made a war crimes protest to Switzerland that had to be investigated at the highest levels and which led back to Bentine's squadron, who had been indenting for more than the usual amount of replacement chemical toilets, claiming the onboard lavatories had been damaged beyond repair by enemy flak. It turned out that every time the toilets got full, rather than have them drained and cleaned on return to base, the earthy Aussies had been ejecting them over German towns and cities as an additional, unofficial, weapon of war, hoping to splash the maximum possible number of Germans as a courtesy detail to go with the bombs. The Germans protested formally about noxious chemical warfare, the Swiss Red Cross formally investigated, and all RAF crews were officially forbidden to empty aircraft toilets over Germany....
- Most gift shops for any rural or semi-rural destination will have novelty items befitting this trope, such as toy animals that "defecate" at will, chocolate candies that resemble the droppings of local fauna, or T-shirts with illustrations and jokes along those lines.
- The "poop cake" story.
- Jack Kim, founder of the World Toilet Organisation, invokes this trope as a means of promoting better sanitation globally.
