Fox in Socks is a children's book by Dr. Seuss, first published in 1965. It features two main characters, Fox (an anthropomorphic fox) who speaks almost entirely in densely rhyming tongue-twisters and Knox (a yellow anthropomorphic character) who has a hard time following up Fox's tongue-twisters until the end.
The book in some ways bears a resemblance to Green Eggs and Ham, another book by Dr. Seuss. Both stories contain two main characters: one who is stubborn and wants to be left alone; the other, a persistent and sometimes annoying opposite.
The book begins by introducing Fox and Knox (sometimes called "Mr. Fox" and "Mr. Knox") along with some props (a box and a pair of socks). After taking those four rhyming items through several permutations, more items are added (chicks, bricks, blocks, clocks), and so on. As the book progresses the Fox describes each situation with rhymes that progress in complexity, with Knox periodically complaining of the difficulty of the tongue-twisters.
Finally, after the Fox gives an extended dissertation on Tweetle Beetles who knock out with paddles while standing in a puddle inside a bottle on a noodle-eating poodle (a Muddle Puddle Tweetle Poodle Beetle Noodle Bottle Paddle Battle), Knox acts on his frustration by stuffing him into the bottle, reciting a tongue-twister of his own:
- A fox is in the bottle where the tweetle beetles stop battling with their paddles in a puddle on a poodle.
The Tweetle Beetle skit was featured in The Hoober-Bloob Highway, a 1975 CBS television special. Here, the skit was part of a job: that of a "famous Tweetle Beetle statistician". If you took on this job, "you could be the world's greatest authority on Tweetle Beetle battlistics, if you study Tweetle Beetles and their ballistic characteristics." It ended by cutting back to the base, with Mr. Hoober-Bloob waving his arms around, covering his ears, and yelling, "Stop it! Stop it! I can't stand it! That world is a vastly cruddy, bloody bore!" The dissertation was read by Bob Holt, the voice of Mr. Hoober-Bloob, using a German impression similar to Ludwig von Drake.

The entire book was translated by the Israeli author and lyricist Leah Na'or into Hebrew as "בא עם גרבים" (Ba Im Garba'im, literally "He Came With Socks"). Some emendations were made to the original text for better rhyming; for example, Knox's name, in this version, is "ברגז" (Bargaz), to rhyme with "ארגז" (argaz, meaning box), and the chicks in the beginning of the book became ducks. Occasionally the translator wrote a new tongue-twister to fit the existing artwork; the entire poem about the cheese trees, for instance, was replaced with an entirely new poem about an elephant who tripped and fell on his nose. This version of the book was published in 1980 by Keter Publications in Jerusalem.
