After returning from the grocery store and putting away the groceries, the owner of a rather large dog noticed that every time he would take the packages out of the bags, the dog's head would move back and forth as if watching a tennis match. 
 

After the last item was removed out of the sack, the dog gave the owner a sad, and pathetic look, and headed for the door.  Thinking that the dog had to relieve himself, he quickly went to open the door.  After about an hour, he noticed that dog had not returned. 
 

After some time, the dog noticed that he had wandered off quite far from home.  Not used to this new strange environment, and thinking about his own selfish attitude about the unpacking of groceries and seeing nothing for himself, he quickly realized that he was lost and said to himself,

"Well, I'll be DOGGONE  !!!"
