This is a compilation of one hundred jokes. Each joke is given a title and is numbered.
They vary in length - from very short (a couple of lines) to fairly long (thirty lines plus).
After the joke there is a commentary which explains the joke for readers who might not have fully understood it.
This could be useful for readers who are not native speakers of English - or even readers from other parts of the English-speaking world where the humour of some jokes may be incomprehensible or opaque.
There is also a list of the jokes by title, and by number.
