Joker, an impudent cad, so funny! (5-2,8)

I believe the answer is:

stand-up comedian

'joker' is the definition.
(I've seen this before)

'an impudent cad so funny' is the wordplay.
'funny' is an anagram indicator.
'an'+'impudent'+'cad'+'so'='animpudentcadso'
'animpudentcadso' with letters rearranged gives 'STAND-UP COMEDIAN'.

I've seen this clue in The Telegraph.
