Comic's party (5)
I believe the answer is:
beano
I believe this clue is a double definition.
'comic's' is the first definition.
(The Beano)
'party' is the second definition.
(I've seen this before)
(Other definitions for beano that I've seen before include "Enjoyable party" , "Comic and informal get-together" , "Informal party" , "binge" , "Function" .)
