A homeless man walks into a diner with enough change for a cup of coffee. 
Seated next to him at the counter, was a well-dressed man with a bowl of 
chili in front of him. A few minutes later, finishing his cup of coffee, 
the homeless man begins to notice that the stranger next to him is not 
eating his chili, but rather just staring at it, looking confused and 
disoriented. Not having eaten in two days, the homeless man asks the 
stranger: "Sir, I'm cold and hungry and haven't eaten in days. If you're 
not going to eat your chili, do you mind if I have it?" With little 
acknowledgement, the stranger simply shoves the bowl in his direction. 
Minutes later, the homeless man, having nearly finished the entire bowl of 
chili, discovers, in the bottom of the bowl - a small pile of dog turds. 
Immediately, the homeless man becomes sick and vomits the chili back into 
the bowl. Finally, the stranger seated next to him turned to him and said 
"I know how you feel, buddy. That's about as far as I got, too."
