Toilet humour, or potty or scatological humour (compare scatology), is a type of off-colour humour dealing with defecation, diarrhea, constipation, urination and flatulence, and to a lesser extent vomiting and other bodily functions. It sees substantial crossover with sexual humour, such as dick jokes. Toilet humour is commonly an interest of children and young teenagers, for whom cultural taboos related to acknowledgement of waste excretion still have a degree of novelty. The humour comes from the rejection of such taboos, and is a part of modern culture. Music Toilet humour is sometimes found in song and rhyme, particularly schoolboy songs. Examples of this are found in Mozart and scatology, and variants of the German folk schoolboys' song known as the Scheiße-Lied (English: "Shit-Song") which is indexed in the German Volksliederarchiv. A children's Spanish musical duo, Enrique y Ana, made a song called "Caca Culo Pedo Pis", which literally translates to "Poop Butt Fart Pee". American musician Matt Farley is known for writing and performing a multitude of songs related to urine, feces, vomit, and various other bodily fluids under the pseudonym The Toilet Bowl Cleaners, including one of his most popular songs entitled "Poop In My Fingernails". Farley has another pseudonym, The Odd Man Who Sings About Poop, Puke, and Pee. Detroit rapper Eminem famously utilises crude humour throughout his discography. His most notorious example of toilet humour was featured on the 2017 album Revival, where he raps "Your booty is heavy duty, like diarrhoea", a line which received extensive lament from critics. The Los Angeles Times comments: "If Hannibal Lecter could have recorded a rap album, this would have been it. Brilliant, sinister, scatological and a parent's nightmare." Performance Paul Oldfield, who performed under the name Mr Methane, performed a stage act that included him farting the notes of music. Joseph Pujol, who performed under the name Le Pétomane (French for "fart maniac"), performed a similar stage act for the Paris music hall scene. Books One of the most popular books about defecation and accidents in toilets is a guide that began as Shitting Pretty and then was relaunched as How to Shit around the World. The children's book series Captain Underpants makes copious use of toilet humor. "Doctor Diaper", "The Bionic Booger Boy", and "Professor Pippy Pee-Pee Poopypants" are among the villains in the series. Television The American comedy duo Tim & Eric have made numerous comedy sketches
