Figures out nothing's funny (5)
I believe the answer is:
comic
'funny' is the definition.
(comic can mean funny or humorous)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for comic that I've seen before include "Wag" , "magazine for kids" , "Professional funny person" , "Stand-up comedian" , "Funny entertainer, often stand-up" .)
