Famous quotes containing the word hair:

    “His hair has the long jesuschrist look. He is wearing the costume clothes. But most of all, he now has a very tolerant and therefore withering attitude toward all those who are still struggling in the old activist political ways ... while he, with the help of psychedelic chemicals, is exploring the infinite regions of human consciousness.”
    —Tom Wolfe (b. 1931)
