Here in Sweden, there’s a classic joke cycle called “All the children-jokes”. They’re kind of like limericks, but less strict. All jokes follow this pattern in some way:
“All the children do x, except [name] because he/she does y.”
Where y rhymes with the name. You can experiment with tense and phrasing as you like. The point is to make y as unexpected and comical in relation to x as possible. Of course, there is also the game of making these jokes as dirty and morbid as possible.
