Old jokes pulled out of fire perhaps (9)

I believe the answer is:

chestnuts

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

'old jokes' is the definition.

I cannot understand how the remainder of the clue works.

(Other definitions for chestnuts that I've seen before include "Common tree-fruits, sometimes roasted" , "often retold stories" , "horses" , "Tree fruits called conkers - some are edible" .)

I've seen this clue in the Sydney Morning Herald.
