Funny girl about to finish work (4)

I believe the answer is:

joky

'funny' is the definition.
(thesaurus)

'girl about to finish work' is the wordplay.
'girl' becomes 'joy' (girl's name).
'about' means one lot of letters goes inside another.
'to finish' says to take the final letters.
The last letter of 'work' is 'k'.
'joy' placed around 'k' is 'JOKY'.

(Another definition for joky that I've seen is " playful".)

I've seen this clue in the Evening Standard.
