re: The meaning of shmoo in hebrew is hard to translate to english. Somewhere between fake and swindle.
There is absolutely no evidence that the name "Shmoo" is derived from the Yiddish word "schmoe", itself a euphemism for the word "schmuck". [1] In short, they were just the opposite. Their name is most likely a designation created by Capp himself in 1948 when the Shmoos first appeared. There is no reference to the etymology of the word in any of the five Shmoo comic books produced in five successive months in 1948, nor in any of the retrospective literature.
