1. Winnie: Mom, I have a joke for you.
  2. Me: Okay.
  3. Winnie: I'm going to tell you that I have a "weak back." And then YOU are going to say "when did you first notice that you have a weak back?"
  4. Me: Got it.
  5. Winnie: (leaves room then comes back in) BOY do I have a weak back!
  6. Me: When did you first notice your weak back?
  7. Winnie: Oh, about a WEEK BACK!
