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

'crazy' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for crackers that I've seen before include "Biscuits; fireworks" , "Crazy - (American) biscuits" , "Crazy (colloq.); biscuits" , "they may be on the table at Christmas" , "Insane" .)

I've seen this clue in The Globe and Mail.
