I think that's the pot calling the kettle black!
This is a very well known phrase/colloquilism in English and it basically means,how can you call me that(usually something bad!)when you are exactly the same,or worse than me?
I won't even attempt to translate it into Spanish because it won't make any sense but there must be a similar phrase in Spanish.
Socorro!

Very funny expression!
In Spain the equivalent is funny too:
Pedro: Mierda...¡No digas esas palabrotas!
Pablo: ....dijo la sartén al cazo! (...said the frying pan to the pot)
También mira esto, hay variacion sobre el mismo tema.
