One day, a carpenter comes home to his modest apartment from a hard days work. He's resting on his couch enjoying the fruits of his labor minding his own business when he hears a knock on the door... He answers the door to see his neighbor bleeding profusely out of his leg. Shocked, he asks, "What happened man?" His neighbor bursts out, "Got into an argument with my girlfriend. Things got heated and she stabbed me in the leg with a kitchen knife. You gotta help me fix my leg!" The carpenter says, "I am not a doctor. I don't know anything about fixing legs." His neighbor says, "Well, can you at least give me money for an ambulance ride?" "Sorry," says the carpenter, "but I don't have any cash on me. Good luck with your leg." The neighbor scoffs, "Fine, thanks for nothing you heartless bastard." The carpenter goes back to his resting, but no sooner than he sits down, he hears another knock at the door... He answers the door to see another neighbor, a young college student holding out his hand with an assortment of pills in it. "Hey, man, which one of these pills will get me fucked up?!" asks the college kid. "I don't know," replies the carpenter, "I am not a pharmacist. All I'll say is, I wouldn't put anything in my body if I did not know what it was." The kid looks at him confused and says, "Fine, thanks for nothing you ignorant fool." The carpenter laughs and goes back to sitting on his couch when he hears yet another knock on the door... He answers the door to see the old man who lives down the hall. The old man says, "Hey, it's my birthday today. Just turned 65!" "Oh, I didn't know that," says the carpenter with a smile,"Happy Birthday!" The old man says, "Since I am old and tired, I do not feel like working any more. So, I was wondering if you would be willing to pay my rent so I do not have to work any more." "Sorry," says the carpenter, "but I do not have that kind of money as I am saving for my own retirement. I guess you'll have to keep working like the rest of us." The old man frowns at him, "Fine, thanks for nothing you greedy punk." The carpenter returns to his couch amused and bewildered. He cannot understand how his neighbors have become so crazy... he then turns on the News and the evening's events become crystal clear.
