Short comic routines or humorous scenes (8)
I believe the answer is:
sketches
'short comic routines or humorous scenes' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sketches that I've seen before include "Rough outlines" , "Preliminary drawings" , "Short comic routines or humorous scenes" , "work for artists" , "Outline drawings or short comic plays" .)
