As the son of God I bet he would have been able to make some rather surprising anagrams!
Perhaps he even did that but the evangelists thought:
making anagrams of "Fisherking" might not really fit in"
Not that long ago I saw a movie trying to present an interpretation of the life of Jesus
and I was happy to see that the authors presented Jesus
in situations where he e.g. had fun with the disciples as they were walking from town to town.
We never hear much of what they did on the way so why not.
Perhaps he anagrammed some:)
