Funny deed he paid attention to (6)
I believe the answer is:
heeded
'paid attention to' is the definition.
(I've seen this before)
'funny deed he' is the wordplay.
'funny' indicates an anagram.
'deed'+'he'='deedhe'
'deedhe' is an anagram of 'HEEDED'.
(Other definitions for heeded that I've seen before include "Took notice of" , "Paid attention to, say warning" , "Listened, minded" , "Took note" , "Respected" .)
