Broad comedy (5)
I believe the answer is:
farce
'broad comedy' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for farce that I've seen before include "Absurd proceedings, perhaps in play" , "Travesty" , "Absurd event; comedy" , "Rookery Nook?" , "Ludicrous stage show" .)
