Quote meaning
Sam and Dean always use pop culture references in their fake names. This time they use the names of actors from the movie We’re No Angels, Robert De Niro and Sean Penn. In the movie they play escaped convicts who pretend to be priests in order to escape the police and cross the border to Canada.
