The hobo knocked at the back door and the lady of the house appeared.
Lady, he said, "I was at the front�"
You poor man! she exclaimed. "One of war's victims. Wait till I get you some food, and you shall tell me your story. You were in the trenches, you say?"
Not in the trenches. I was at the front�
Don't try to talk with your mouth full. Take your time. What deed of heroism did you do at the front?
Why, I knocked, but I couldn't make nobody hear, so I came around to the back.
