Sherlock Holmes (TV series)/Funny

At the end of "The Copper Beeches", this conversation that follows Watson reading aloud his canonical journal entry:

Watson: There, Holmes. Your verdict?
Holmes: An admirable account, Watson.
Watson: Oh, you don't think I've put too much color and life into it?
Holmes: *turns around in his seat to face Watson* Oh, my dear friend, I humbly defer such considerations to your excellent literary judgment. *turns back to the camera so that Watson cannot see his face*
Watson: *proudly smiles* Good!
Holmes: *gives a sarcastic, Fascinating Eyebrow look to the camera*

In "The Greek Interpreter", when Holmes, Watson, and Mycroft are rushing to catch the train the murderers are on, the following exchange occurs:

Sherlock: Mycroft!
Mycroft: I'm not built for running, Sherlock!

- And then, a moment later when they're in the compartment, Sherlock is calmly smoking a cigarette... right next to the sign that says "Smoking is Strictly Prohibited in this Compartment."
At the beginning of "A Scandal in Bohemia" Watson offered his hand to the king-in-disguise and was ignored. At the end of the episode, the King offers his hand to Holmes, who turns away -- and Watson steps in, gives a sharp shake and a very polite nod, and waves the man out.
In "The Six Napoleons", Lestrade is waiting in the sitting room for Holmes and Watson to return, looking bored out of his mind...until he catches sight of the papers on the table beside Holmes' chair and so nonchalantly starts to finger through them...and while this is going on Holmes watches him through the half-closed doorway, waves Watson over so that he can see, and then Holmes and Watson quickly duck back down the hall and "enter" loudly, giving Lestrade the chance to stop snooping and act all innocent when they come in.
Holmes giggling when he hears Shinwell Johnson's nickname "Porky" for the first time in "The Illustrious Client".
