In reality broadcast oafs attract fame (2,1,6,2,4)
I believe the answer is:
as a matter of fact
'in reality' is the definition.
(I've seen this before)
'broadcast oafs attract fame' is the wordplay.
'broadcast' is an anagram indicator.
'oafs'+'attract'+'fame'='oafsattractfame'
'oafsattractfame' is an anagram of 'AS A MATTER OF FACT'.
(Other definitions for as a matter of fact that I've seen before include "in reality" , "Actually" .)
