- Mrs. Wead: [after Doc has concluded that her daughter has an ulcer, not food poisoning] I think, I think you did actually mention the possibility that it could be.
- Dr. Martin Ellingham: The possibility, yes, but not the certainty or even the probability. Do you know the difference between those words?
- Becky Wead: Don't talk to my mum like that!
- Dr. Martin Ellingham: I'll talk how I want. It's my surgery. The tests on your feces rule out food poisoning. Is there any part of that sentence that either of you are struggling with? Good. Take this and go away.
