Input:  Person1:       Julie , what's on the tube ?  
 Person2:nothing but bench of commercials . These days the amount of commercials is amazing .  
 Person1:        yeah . Maybe we can change to another channel . what about the sports channel ? Let's see if there's a game on .  
 Person2:okay . Nope , it's a replay of yesterday's soccer match between Brazil and Spain .  
 Person1:        it was a good game , but not good enough to watch again . Keep surfing .  
 Person2:alright . Hmm , this movie is a rerun ... I don't know how many times I've seen this show ... Commercial again ... and a replay of the talk show ... oh no , this show is terrible , you don't wanna watch it .  
 Person1:        oh , what is it ?  
 Person2:it's a total rip-off of an American reality show , but the imitation is unbearably clumsy .  
 Person1:        oh , I know this kind of shows . Sometimes they really piss me off . If I wanted reality , I'd go outside .  
 Person2:yeah ... it seems what we have on TV now are either repeats , or commercials , or low-quality shows . There's really nothing to watch .  
 Person1:        I don't get it . We have more than 100 channels and there's still nothing good on ! Maybe we should just turn off the TV , get outside , and do something real .  
 Person2:cool .
