Funny guys finally left a scrap (7)
I believe the answer is:
oddment
'a scrap' is the definition.
(synonyms)
'funny guys finally left' is the wordplay.
'funny' becomes 'odd' (I've seen this before).
'guys' becomes 'men' (guy can mean a man).
'finally' says to take the final letters.
The last letter of 'left' is 't'.
'odd'+'men'+'t'='ODDMENT'
(Other definitions for oddment that I've seen before include "Curiosity, peculiarity" , "Scrap" , "Piece left over, no match" , "Just a bit left" , "One of a broken set" .)
