review its kind of a funny story

Maybe it has some witty dialogues. Characters saying smart and humorous things can make a story funny.

I don't know who wrote it as the title alone doesn't give any indication of the author.

I'm not sure specifically as the title is quite vague. It could be about any number of humorous events or situations.

There's no way to tell for sure just from that statement. It could be, if someone was writing about a book on Gradesaver and thought the whole experience of reading the book and using the site's resources was a funny story. But it also might not be a book review at all and could be about some other aspect of Gradesaver, like an interaction with the website's features or other users.

The humor might come from the way the story is told. If it has a lot of vivid descriptions of funny expressions or sounds. Like in a story where a parrot imitates a person's sneeze in a very exaggerated way. It makes the story more engaging and funny.

The unexpected twists usually make it funny. For example, if a character is supposed to be very serious all the time but suddenly does something completely silly like dancing in the rain without any reason. That kind of deviation from the norm can be a great source of humor.

There could be a goofy animal character. Maybe a cat that always tries to catch its own tail and ends up spinning around in circles.

A story can be 'kind of funny' when there is an unexpected twist. For example, if you expect someone to be really good at something but they end up being completely hopeless at it. Like a professional athlete who can't ride a bike.

It could be about a clumsy character who is always getting into comical accidents.

They often have a great sense of absurdity. They can create situations that are completely out of the ordinary but still seem believable within the context of the story. For instance, a character might suddenly start talking to animals in a very normal way as if it's an everyday occurrence.
