If you want to increase team productivity, relieve stress, and be happier at work, you could hire a bunch of workplace consultants, invest in scream therapy, and put Pharrell Williams on repeat—or you could just read Humor That Works.

Written by Andrew Tarvin, the world’s first Humor Engineer, this a business book on humor. No, that’s not an oxymoron. It really is a business book and it really is about getting better results by having more fun. Because people who use humor in the workplace are more productive, less stressed, and happier. No joke; sources included.

And you’ll have fun doing it.
