Yes, sometimes because one of the members of my family wants to know how a word or a phrase sound in English or because they, or me, want to hear the voice of the actor/tress, but in many times at least from my part I do it just wondering...

I watch things like Modern family, and although the serie is traduced well, in many occasions there are jokes that are specifically did it in english and adressed to english people.
Well, if Modern Family is wonderful in Spanish in English you understand many things and make the serie even better.
