Anda que no sabes nada tú.

[ROBINDESBOIS]

CAN any body translate this sentece? SAber nada here is used sarcastically meaning the opposite.

[Perikles]

Just a guess:

Come off it! - are you telling me you know nothing?

[ROBINDESBOIS]

That would be:
ANda ya, me vas a decir que no sabes nada.

It´s somethign like :
You little rascal !
