But who can fear a kzin who is having his ears scratched?

One day, as one does, I searched for this line from Ringworld: "But who can fear a kzin who is having his ears scratched?"

Some fine fellow provided it as an example for the use of "scratched" in a Hungarian-English dictionary.

De ki félne egy kzintől, aki hagyja a füle tövét vakarni?
