Malicious (foaled 1927) was a Thoroughbred race horse sired by the winner of the 1917 Kentucky Derby, Omar Khayyam, out of Ridicule (by Black Jester).
He made a personal appearance at San Francisco's 1939 Golden Gate International Exposition, had people promoting merchandise in his name, and was interviewed on the radio.
Morton Cathro, a retired newspaperman, wrote of seeing Malicious in the last days of his career: "As a teenager in the autumn of 1939, this writer witnessed a series of Saturday marathons at Bay Meadows for top routers.
The weary road warrior, who hadn't started since that spring at Santa Anita, made his patented late surge to gain fourth in a blanket finish.
That was his final race in the U.S. On Jan. 28, 1940, at age 13, one of the toughest iron horses of all time closed out his gallant career—a marathon in itself—by running second at Agua Caliente.
