Since today’s strip does nothing to move the story along, let us attempt to get at the genesis of “finito binito [sic]”:
From Wikipedia, the free encyclopedia
Finito Benito comes from the North American Aviation B-25J Mitchell Medium Bomber airplane named “Finito Benito Next Hirohito.” This B-25J bomber was attached to the 12th Air Force, based in Naples late in World War II.
The name Benito refers to the Italian dictator, Benito Mussolini. Hirohito refers to the name of the Japanese emperor during World War II. Italy and Mussolini fell in 1943 while Japan and Hirohito fell in August 1945…[t]he name…was painted in red on the upper surfaces of the wings, as opposed to the usual placement on the nose of the airplane.
