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

I can't explain the remainder of the clue.

(Other definitions for crackers that I've seen before include "Yanks open these" , "they may be on the table at Christmas" , "full of bad jokes at Yuletide?" , "Biscuits; fireworks" , "Mad - biscuits" .)

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