Mr Average entertains them in surprising ways (3,2,3,6)
I believe the answer is:
man in the street
'mr average' is the definition.
'man in the street' can be an answer for 'average' (thesaurus). I am not sure about the 'mr' bit.
'entertains them in surprising ways' is the wordplay.
'entertains them' can be anagrammed to 'MAN IN THE STREET'.
Though, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for man in the street that I've seen before include "Rough sleeper perhaps" , "Anybody" , "Tom, Dick, or Harry" , "who's just been evicted?" , "no one special" .)
