Holmes: What in heaven's name are you doing up there?
Watson: This, sir, is where the cabby usually sits.
Holmes: No, really, Watson?
Watson: I'm sorry, sir. I think you've made a mistake. My name isn't ... It's Sedgeley, sir.
Holmes: May I give you some advice, 'cabby'? The corners of your beard are badly in need of repair. Most extraordinary behavior! Ah, a legitimate carriage. Cabby! Cabby! Good day, 'Sedgeley'.
