- Dr. John H. Watson: Yes, it wasn't bad even though I do say so myself
- Paul: He wanted to kill me and though he was a friend
- Sherlock Holmes: That should teach you a lesson, Paul. No one's a friend who encourages a boy to run away from school. Why, what would have become of Doctor Watson if he hadn't never gone to school. Well, it's very simple. He'd never had been able to accomplish that trick.

- Dr. John H. Watson: In dropping that counterweight, young man, I had to know the speed of falling objects, the theory of weight and counterweight, and of stress and resistance . Now, if I hadn't studied physics, there is no telling what would have happened to you.
- Paul: I never thought of that
- Dr. John H. Watson: No, of course not. Well, you just think of that from now on.
- Sherlock Holmes: Watson, did you really have all that in mind when you pulled that rope ?
- Dr. John H. Watson: Oh well, I did really, of course Oh did you ?
- Sherlock Holmes: Oh did you ?
- Dr. John H. Watson: uh-huh
