Enjoy a snide sort of joke? (3)

I believe the answer is:

dig

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

'enjoy' is the definition.
(to dig can mean to appreciate or 'get')

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for dig that I've seen before include "A brief archeological excavation" , "Briefly, an archaeological excavation" , "Sly remark; excavate" , "Use a spade" , "Understand" .)

I've seen this clue in the Evening Standard.
