One Hundred Mirthful Jokes

This is a compilation of one hundred (generally inoffensive) jokes, some short, some long. Each joke is given a title and is numbered, and there is a list of the jokes by title and a list by number.
They vary in length - from very short (a couple of lines) to fairly long (thirty lines plus).
After the main body of jokes there is a section which explains each one for readers who might not have fully understood the joke.
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 (or humor) of some jokes may be incomprehensible or opaque.
