Lt. Col. Henry Blake (1972)
Not far behind Gilligan and Good Times' J.J. in television's bucket hat pantheon is Lt. Colonel Henry Blake of M*A*S*H. Actor McLean Stevenson had originally auditioned for the lead role of Hawkeye, but when that part went to Alan Alda, Stevenson became the man who insisted on wearing his fishing-lure-adorned bucket hat in the middle of a war. For Blake, the hat was a comforting touch of home, not unlike Linus's security blanket. We can only assume he had it on when his plane was shot down over the Sea of Japan.
