Good movie extract performance by this great little Spanish actress,  Ana Torrent  :-)

Mira:  Cria Cuervos (1976) Ana Torrent     Raising Ravens    Pasted from <http://www.imdb.com/title/tt0074360/>

 Cría cuervos-  song: Por qué te vas? (Why are you leaving?)

 The whole sentence is Cria cuervos y te sacaran los ojos = Raise crows and they'll peck your eyes out. Which means that you raise or help another person that turns to be ungrateful with you. It's somehow similar to "bite the hand that feeds them". For example, on Spain when a child is disrespectful with his/her parents, they say "aaayyy, cria cuervos!!". 

Enjoy!
