YOU SAID:
When pigs fly the cows will all murder each other
INTO JAPANESE
豚が飛ぶと、牛はすべて互いに殺される
BACK INTO ENGLISH
As pigs fly, all the cows are killed each other
INTO JAPANESE
豚が飛ぶと、すべての牛が互いに殺される
BACK INTO ENGLISH
As pigs fly, all the cows are killed each other
That didn't even make that much sense in English.
