Pa miscounted and played joker (5-2,8)
I believe the answer is:
stand up comedian
'joker' is the definition.
(I've seen this before)
'pa miscounted and played' is the wordplay.
'played' indicates anagramming the letters.
'pa'+'miscounted'+'and'='pamiscountedand'
'pamiscountedand' with letters rearranged gives 'STAND UP COMEDIAN'.
(Other definitions for stand up comedian that I've seen before include "joke teller" , "joker" .)
