I'm a little stuck... Click here to teach me more about this clue!

'funny' is the definition.
(comic can mean funny or humorous)

'business with figures' is the wordplay.
'business' becomes 'co' (short for company).
'with' says to put letters next to each other.
'figures' becomes 'mic' (I can't justify this - if you can you should give a lot more credence to this answer).
'co'+'mic'='COMIC'

Can you help me to learn more?
