Have you ever wondered who made the call on imperial measurements, collective nouns for animals, horoscopes and Olympic sports? What were they thinking? And why do parents insist on naming their children after cities, cars and smoothie ingredients (Paris, Mercedes and Kale, we're looking at you...)?

The Guy Who Decides, Jimmy's first book for adult readers, expands upon his hilarious videos lampooning the absurd conventions and rules of our modern world through the outlandish characters of The Guy Who Decides (who appears to be several martinis deep at all times) and his underling, Jason. Meanwhile, from Brighton to Byron Bay and beyond, prepare to meet a bunch of Australians who are as funny/scary as they are uproariously familiar!
