One Fish Two Fish Red Fish Blue Fish is a 1960 children's book by Dr. Seuss. A simple rhyming book for learner readers, it is a book with a freewheeling plot about a boy and a girl, and the many amazing creatures they have for friends and pets. One Fish Two Fish Red Fish Blue Fish was part of the Beginner Book Video series which included Oh, the Thinks You Can Think! and The Foot Book.
Rik Mayall narrated this story as part of a HarperCollins audiobook that also includes The Lorax, Dr. Seuss's ABC and How the Grinch Stole Christmas.
The Fedora Core 2 Test 2 announcement contained a "One bug, two bugs, tar bugs, su bugs" poem that resembled and parodied the original book as well as The Cat in the Hat, another poem book by Dr. Seuss.
