"ON APRIL 27, 1970, WALTER BRENNAN WAS INDUCTED INTO THE HALL of Great Western Actors at the Cowboy Hall of Fame's annual awards ceremony in Oklahoma City. After listening to several speakers lavish praise on him, he stood up and said, "Other than that, I'm a dirty old man." He often liked to undercut a compliment with a self-directed jibe. But as his son Andy said, his father was thrilled with the honor. Later Brennan donated his papers to what is now the National Cowboy & Western Heritage Museum."
