Crazy family - might be responsible for slip (6,4)

Ross

I believe the answer is:

banana skin

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

'be responsible for slip' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'crazy family' is the wordplay.
'crazy' becomes 'bananas' (I can't justify this - if you can you should give a lot more credence to this answer).
'family' becomes 'kin' (synonyms).
'bananas'+'kin'='BANANA SKIN'

'might' is the link.

Can you help me to learn more?

(Other definitions for banana skin that I've seen before include "potential hazard" , "something to cause embarrassment" , "A disaster waiting to happen" , "Potential disaster" , "that could lead to one's downfall" .)
