All six blokes initially entertained by funny, garrulous type
I believe the answer is:
gasbag
'garrulous type' is the definition.
(I've seen this before)
'all six blokes initially entertained by funny' is the wordplay.
'initially' says to take the initial letters.
'entertained by' means one lot of letters goes inside another (I've seen this in other clues).
'funny' becomes 'gag' (I've seen this before**).
The first letters of 'all six blokes' is 'asb'.
'asb' placed within 'gag' is 'GASBAG'.
(Other definitions for gasbag that I've seen before include "One going on" , "He likes to talk" , "I can't shut up" , "Person who talks too much - or a balloon" , "Garrulous type" .)
