Hunter S. Thompson, journalist and creator of Gonzo Journalism, received an honorary doctorate from the Universal Life Church in the late 1960s. Thompson often insisted on the title, as well as his alter ego Raoul Duke in Fear and Loathing in Las Vegas who claimed to be a "Doctor of Journalism".
Billy Graham is regularly addressed as Dr. Graham, though his highest earned degree is a BA in anthropology from Wheaton College. He holds 20 honorary doctorates and has turned down nearly twice as many.
