Cluin, it's true that the line in question was from "The Great Race" but it was used as a comic tribute to "The Prisoner of Zenda" where the villain, played by James Mason, says, "I shall live to fight another day.", as he leaps from a castle window to avoid swordplay with Stewart Granger.
Legendary folksinger, George Britton, used to torture his kids with gems like "Hasta Lumbego". That they still speak to him is a wonder.
