Dr. Seuss' Mr. Knox is known from the beloved children's book "Fox in Socks". Mr. Knox does not care at all for tongue twisters and complains through the whole book about the tongue twisters. By the end of the book Mr. Knox gets mad at Mr. Fox and stuffs Mr. Fox into a bottle and called it  "...a tweetle beetle noodle poodle bottled paddled muddled duddled fuddled wuddled fox in socks, sir!" Mr. Knox is a yellow fellow who gets irritated easy and does not like Mr. Fox's silly rhymes.
