It's a collection of jokes (apparently) written by children. They aren't funny, in the sense that they make no damn sense. Yet, lots of them are funny in the sense that they are completely ridiculous but you can see what the child was trying to do, i.e. deliver a joke in the same style as they have heard before, e.g.
Knock, knock
Who's there?
A ladybug.
Ladybug who?
A LADYBUG. I just SAID that.
