A man is in line at Walmart holding a bag of dog food when a lady behind him asked:
"Do you have a dog?"
Annoyed by the stupid question, he replied:
"No, actually this if for me. You see, it is part of a terrific weight loss diet program I am on. I used to weigh 100 pounds more than I do now. I stopped the diet for a while I was in the hospital with a broken hip."
"Ohh, did you get too thin? asked the lady.
"No, one day I was crossing the street and when I stopped to lick my balls, a truck hit me"
