Person2:I believe some shows are quite informative and interesting . Take this show for example , it examines American xenophobia and how it might conflict with the American dream , with hilarious results .
Person1: really ? that's interesting !
Person2:yeah.Oh , here it comes ! why don't we watch it together ? they are going to have a court debate in this episode . It should be good .
