J-files

I read a new book, it's called J-files.
It's about in the big factory, it has a j-files team, top secret. What they do? They make funny jokes, and connect to internet, so the people will read it. They have a big machine, to see how many people is happy in world. It has a list, 1 to 10, if the red line on ten, it's means super happy, if it's on the 1, it means very very very not happy.
But one today, the j-file team can't think so many funny jokes. the boss is so angry, but they still can't think funny jokes, boss run to home, she see so many people angry, because no jokes!
Suddenly, she hear so many funny jokes, oh, it's in a classroom!
She write the jokes and run to the house, write in the computer, and the people are happy again.
I think this story about jokes made words happy.
