Andy Griffiths is a popular, bestselling kids author from Australia and is Terry's best mate. The Day My Butt Went Psycho! is his first title published in the United States. He has won rave reviews from kids and adults alike for The Day My Butt Went Psycho! and his other hilarious titles. Andy lives with his wife and two daughters in Melbourne, Australia where he divides his time between storywriting and butt-fighting.
Andy gets his wild and funny story ideas from ordinary life, he is a passionate advocate for literacy and thrives on having an audience (he's been the lead singer in a rock band). When he is not writing kids books, he is in constant demand to speak at schools (he's worked as a high school teacher) and writing workshops. His easy going manner, and his side-splitting sense of humor (he's been a stand-up comedian) all combine to make him popular with students of all ages.
Terry Denton is a bestselling and award-winning writer and illustrator based in Melbourne, Australia. He is Andy's best mate. Among other things, he worked on the Horrible Science series for Scholastic UK. He lives by the beach with his wife and three kids.
