SOMEWHAT MIXED.

  "What's the matter?"
  "Sam, who am I?"
  "Why, you are yourself—Bob Harrison, ain't you?"
  "No, far from it."
  "Why, what's the matter?"
  "Well, sir, I am so mixed up I don't know who I am."
  "Don't take it so hard to heart."
  "I can't help it."
  "Well, sir, what's the matter?"
  "Why, I am married."
  "Married! Why, sir, you should be happy."
  "Yes, but I ain't."
  "Why, all married men are supposed to be happy."
  "Yes, but how many are so?"
  "Well, sir, as I said before, don't take it so hard; tell us all about it."
  "Well, Sam, I'll tell you how it is. You see I married a widow, and this widow had a daughter."
  "Oh, yes, I see how it is; you have been making love to the daughter."
  "No; worse than that! You see my father was a widower, and married that daughter; so that makes my father my son-in-law, don't it?"
  "Well, is that all?"
  "No; I only wish it was. Don't you see, my stepdaughter is my step-mother, ain't she? Well, then, her mother is my grandmother, ain't she? I am married to her, ain't I? So that makes me my own grandfather doesn't it?"
