As the prolific papa of "gonzo" journalism, Hunter S. Thompson left behind a trail of classic books, including 1966's Hell's Angels: The Strange and Terrible Saga of the Outlaw Motorcycle Gangs and 1973's Fear and Loathing in Las Vegas. Thompson's personal motto was "When the going gets weird, the weird turn pro," which he did with a cigarette clenched between his teeth and a bucket hat splayed on his bald head. The great man's bucket became so iconic that Johnny Depp required one to get into characters as Thompson when he starred in the movie adaptation of Fear and Loathing in Las Vegas.
