Can you read that quote above out loud? A bit of a tongue-twister, isn't it? Well, you ain't seen nothing yet.

''Fox in Socks'' is a 1965 children's book by Creator/DrSeuss which, while not so well known as ''Literature/TheCatInTheHat'' or ''Literature/HowTheGrinchStoleChristmas'', is probably the clearest example of his approach to writing for his target audience. Specifically silliness, which, in the form of tongue-twisters and some absurd situations, is the vehicle used to teach children some simple words. Said Fox in Socks leads Knox out of the Box through lots of wordplay knots.

The book's climactic Tweedle Beetle sequence was animated for Seuss' ''The Hoober Bloob Highway'' television special.

!!This book provides examples of:

* ButtMonkey: Knox.
* CircularReasoning: Luke takes licks in lakes his duck likes, and vice versa.
* {{Dedication}}: It is the first Beginner Book to have one. Mitzi Long was a friend of Suesses, and Audrey Diamond was his second wife. The Mt. Soledad Linguistic Laboratories is a fictional place - Suess always said Audrey was the only adult who could get through his tounge twisters on the first try.
* FeetFirstIntroduction: The lower half of the socked-fox is over the title page.
* HumanlikeFootAnatomy: Both Fox and Knox (whatever the Knox is)
* {{Narrator}}: The book beings with a narrator explaining all the things seen, the way most Beginner Books do. ("Fox. Socks. Box. Knox.") That's followed by two pages where the fox's mouth is open but it is not immediately clear if he is speaking. When the chicks with bricks and block come, the [[SwitchingPOV Fox and Knox unquestionably take over the speaking roles]] for the rest of the book.
* TheOneWhoWearsShoes: Or socks, in this case. The fox is only seen separate from the socks on the first page, and his feet are obscured.
* OralFixation: Luke Luck and Luke's Duck lick lakes... for some obscure reason.
* ScrewySquirrel: The Fox.
* TheStinger: The inside of the rear cover of the book says "''Now'' is your tongue numb?"
* SnicketWarningLabel: "Take it slowly, this book is dangerous!"
* ThereIsOnlyOneBed: The sick chicks all tocking together in bed.
* TongueTwister: The whole book.
