Famous quotes containing the word muscles:

    What is this beast, she thought,
    with muscles on his arms
    like a bag of snakes?
    What is this moss on his legs?
    What prickly plant grows on his cheeks?
    What is this voice as deep as a dog?
    Anne Sexton (1928–1974)

    The indispensable ingredient of any game worth its salt is that the children themselves play it and, if not its sole authors, share in its creation. Watching TV’s ersatz battles is not the same thing at all. Children act out their emotions, they don’t talk them out and they don’t watch them out. Their imagination and their muscles need each other.
    Leontine Young (20th century)

    As the strong man exults in his physical ability, delighting in such exercises as call his muscles into action, so glories the analyst in that moral activity which disentangles.
    Edgar Allan Poe (1809–1845)
