Curly or Moe (6)
I believe the answer is:
stooge
'curly or moe' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stooge that I've seen before include "A comedian's assistant, butt of his jokes" , "Partner who is the butt of comedian's joke" , "Comedian's assistant-victim" , "Toes go wrong for the scapegoat" , "Comedian's foil" .)
