Dim Tuscan cop gets busted — one might joke about it (5,2,5)

I believe the answer is:

stand up comic

'one might joke about it' is the definition.
(type of comedian)

'dim tuscan cop gets busted' is the wordplay.
'gets busted' indicates anagramming the letters (a busted or broken order of the letters).
'dim'+'tuscan'+'cop'='dimtuscancop'
'dimtuscancop' anagrammed gives 'STAND UP COMIC'.

I've seen this clue in The Guardian.
