Crazy solvers! (8)
I believe the answer is:
crackers
'crazy' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for crackers that I've seen before include "Thin biscuits for cheese" , "Yanks open these" , "nuts and > bananas" , "Pulled at parties!" , "Not being sensible" .)
