A club, perhaps, with character (4)
I believe the answer is:
card
This clue is a double definition.
'a club perhaps' is the first definition.
(clubs is a playing card suit)
'character' is the second definition.
(both can mean a humorous person)
'with' is the link.
(Other definitions for card that I've seen before include "One taken in hand" , "Comic" , "Christmas greeting" , "Heart or club, say?" , "one in a suit" .)
