Failure is not an option.
Vayyrrzznn buhhjuhnn.
(Note that the average zombie is not likely to say this: The pronounciation of the word “option” is too difficult for the average zombie.A zombie is more likely to say, “Failure is not O.K.” which is pronounced “Vayyrrzznnohh gayyy.” But both translations were provided. Zombies are not one size fits all!)
