[ WP ] There 's something odd about the door-to-door salesman standing on your porch .

It's Sunday. A nice, sunny Sunday. About ten in the morning, people are just waking up from their slumber. 
 
 Yet there is someone ringing the bell to Mark's home. Who would wake him up at this hour, on Sunday? 
 
 He puts his flippers and head to the front door, cup of coffee in hand. He is met by a man dressed in a sharp suit, who starts talking like a machine gun. 
 
 `` Hellosirwouldyouliketoseethenewimprovedcarpetsbytheredcarpetingcompany? presentingitsnewvarieties: redlightblueand...'' 
 
 Mark opens his mouth like a fish out of water, his crusty eyes still not processing the information before his eyes. 
 
 `` Thenewcarpetscanwashyourfeetwashyourarandmassageyourdog...'' 
 
 And that's when he notices it: there's something weird about this salesman! Something's odd with him, but he ca n't quite place his finger on it. 
 
 `` Andwe'repressentingthenewastroturfcarpetidealforsoccerfieldsandhockeymatches...'' 
 
 Is it the fact that the salesman's head is grey? No, that ca n't be. Many people have grey heads. Is it that his face is square? But many people he knew had square jaws and that did n't make them weird. And, even if the salesman's arms are thinner than a bird's leg, that does n't mean anything. 
 
 `` No, thanks.'' Mark says, opening his lips to say something for the first time today. 
 
 He closes the door and then he realizes: The salesman was a robot!
