“Whenever I say the word ‘exercise’ I wash my mouth out with chocolate” (or “Every time I hear the dirty word ‘exercise’ I wash my mouth out with chocolate” or “Exercise is a dirty word. Every time I hear it, I wash my mouth out with chocolate”) is a jocular anti-exercise saying that has been printed on many images.

“‘EXERCISE’ is such a dirty word in my household that whenever I even think of it, I wash my mouth out with chocolate. - Leonore Fleischer in Publishers Weekly” was printed in The Reader’s Digest in 1992. Leonore Fleischer is an author who was born in 1932. “Exercise is a dirty word, every time I hear it, I wash my mouth out with chocolate!”—a shortened form—was posted on the newsgroup rec.crafts.textiles.needlework on March 25, 2003.

“‘Every Time I Hear the Dirty Word ‘Exercise’ I Wash My Mouth Out With Chocolate’—Richard C. Smith of Springfield” was printed in the Washington (DC) Post on August 4, 2003. “Whenever I say the word ‘exercise’ I wash my mouth out with chocolate. *from a magnet on my aunt’s fridge* haha!” was posted on Twitter by Lee McDerment on December 30, 2008.
