Runcibl'd Stiltskin: A Spooner Selfie

Which nonsense dispenser gives  

good as it gets...?

PlaysWellWithLetters.
     (Then who's least offensive
to lovers of pets…?
LaysWellWithPetters...?)
     Moral:
Carroll 'n' Lear...? 

They've little to fear:

both be biting. 

(Their barks, too: superior, dear.)
