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.
The humor in it, of course. If it's a story, the way the events are narrated in a comical way can make it interesting. Maybe there are unexpected turns or absurd characters.
It could be that the characters in 'Blink' are all really eccentric. Their strange behaviors and reactions to different situations might be what makes the story so funny. For instance, if there's a character who always does the opposite of what is expected every time they blink, that would be quite comical.
Well, it involves a lot of misunderstandings and clumsy moments. For example, I was trying to do a magic trick for my niece. I thought I had it all planned out, but I ended up making the card disappear into my own sleeve instead of making it reappear in my hand like I was supposed to. The look on her face was priceless.
The unexpected things that happen in it. For example, when I went to the grocery store, there was a parrot sitting on a shelf. It started talking to people as they walked by. It said things like 'Hello, beautiful' and 'Nice hat'. No one knew where it came from, and the looks on people's faces were priceless.
The unexpectedness. In a funny story, things don't go as planned. Like in the story of the dog chasing its tail, we don't expect the dog to be so clueless about its own body part. It's this deviation from the norm that makes us laugh.
Maybe the unique characters in it. If there are characters with very distinct personalities, like a super shy person in a very loud and chaotic situation, it can be really funny.
Zach Galifianakis himself is a big factor. His comical appearance and the way he acts in a very unorthodox manner can be very humorous. He often plays characters that are a bit odd or out - of - place, and that contrast creates laughter.
Well, without knowing the specific story, it could be funny because of the characters in it. Maybe they do some silly things or have really strange conversations.
A story can be 'kind of a funny story' if it has unexpected elements. For example, if a character who is supposed to be very serious suddenly does something silly like slipping on a banana peel.
