Fictional character who says "A day without a friend is like a pot without a single drop of honey left inside" (4)
I believe the answer is:
pooh
(Other definitions for pooh that I've seen before include "A.A. Milne's lover of hunny (sic)" , "Bear of very little brain" , "Impatient sound" , "4 - expression of disgust" , "What a stink!" .)
