I believe the answer is:

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

'comedian' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?

'french shrewdness?' is the wordplay.
'french' becomes 'norman' (Normandy is a part of France).
'shrewdness?' becomes 'wisdom' (I can't justify this - if you can you should give a lot more credence to this answer).
'norman'+'wisdom'='NORMAN WISDOM'

'displaying' is the link.

Can you help me to learn more?

(Other definitions for norman wisdom that I've seen before include "English comic actor, famed for hapless on-screen roles, d. 2010", "Pearls from Rouen, maybe", "funny little bloke in a flat cap", "old actor", "British comedian, once a cult figure in Albania, d. 2010".)
