Input:  Person1:     what are you watching on the telly ?  
 Person2:  there's a great sitcom on Channel 3 that stars in about three minutes .  
 Person1:      which one is that ?  
 Person2:  the office . Have you watched it ?  
 Person1:      I've seen the British version and loved it , but have never seen the American version .  
 Person2:  it's almost exactly the same . I think it's a hilarious show .  
 Person1:      what are you watching now ?  
 Person2:  they're just showing highlights of American Idol from last night right now .  
 Person1:      I can't stand American Idol ! I think it's really over-rated .  
 Person2:  I couldn't agree with you more .  
 Person1:      have you got satellite , cable , or digital TV ?  
 Person2:  we have digital TV . It's amazing though---even with 100 channels , there's often nothing on that I'd want to watch !  
 Person1:      do you watch a lot of TV then ?  
 Person2:  I guess so . I'm bit of a couch potato . How about you ?  
 Person1:      I don't have a TV at home , so I rarely watch anything . Is there anything worth watching after the office ?  
 Person2:  there's actually a documentary on the history channel later on that I'd like to watch . Do you want to stay and watch it with me ?  
 Person1:      why not ? I don't have anything better to do !
