One Fish, Two Fish, Red Fish, Blue Fish is a 1960 children’s book by Dr. Seuss. It is a simple rhyming book for beginning readers, with a freewheeling plot about a boy and a girl named Jay and Kay and the many amazing creatures they have for friends and pets. Interspersed are some rather surreal and unrelated skits, such as a man named Ned whose feet stick out from his bed, a creature who has a bird in his ear, and one man named Joe who cannot hear the other man’s call.
As of 2001, over 6 million copies of the book had been sold, placing it 13th on a list of “All-Time Bestselling Children’s Books” from Publishers Weekly. Based on a 2007 online poll, the United States’ National Education Association labor union named the book one of its “Teachers’ Top 100 Books for Children.”
