Another free day on the meme. How about talking about some cannon in-jokes that the writers are working into the show, along with a few things that they've adapted brilliantly to the modern day? Holmes = cannon. Sherlock = modern day.
Mrs. Turner next door. This one about made me fall out of my chair the first time I heard Mrs. Hudson say it. What this is talking about is the simple fact that Doyle never kept notes on what he was writing - and that makes it ten times as hard to figure anything out - so in the first story the landlady at 221B was Mrs. Hudson. She's not named at all in the second one and then in the third, suddenly she's Mrs. Turner. In the fourth and the rest of the cannon, she's Mrs. Hudson. Holmes scholars have driven themselves crazy trying to work out who Mrs. Turner is and why she was there. Granted it was probably just one of Doyle's mistakes, but this is creative dealing with it. :)
"It's a three patch problem." (ASiP)
I'm using Jeremy Brett as Holmes for the cannon as Paget didn't always draw what I'm looking for. Plus, I think he's hot. *Grins* So, Holmes smoked a lot. There were times when Watson thought the room was on fire because of the tobacco smoke. I can't recall the case right off the top of my head, but when questioned what course of action he was going to take, Holmes replies "To smoke. This is quite the three pipe problem and I beg you not speak to me for fifty minutes." In the modern version, it's a three patch problem. Again, about fell out of my chair laughing.
"I prefer to text"
In one of the later cannon stories, Watson receives a telegram from Holmes telling him "if come to Baker Street if convenient. If inconvenient, come all the same." Watson remarks that Holmes would never write a letter or make a call (telephone was in it's infancy about this time) when a telegram would do. Take this to modern times and you have the text message. I found this one to be brilliantly done. Gave me the giggles, but not as hard.
Sherlock shooting the wall when he was bored. This one comes from my all-time favorite opening in the cannon stories. The Musgrave Ritual, where Watson bemoans that firearms practice should be strictly an outside past time. Holmes adorned the wall opposite his armchair with a patriotic VR done in bullet pocks. We know that Sherlock is a little less enamored with the Queen in modern times, so they had a smiley face for him to shoot at. In my opinion, with that wallpaper, it can only be an improvement.
In The Great Game, Sherlock remarks that he would be lost without his blogger. This is probably the only line that annoys me because it doesn't read well. The original is Holmes telling Watson that "I would be lost without my Boswell." Yeah, I know, only cannon fans would get that had they left it in original form, but the change just doesn't work for me.
Finally, the great wound debate. I'd have to have the cannon in front of me to recall exactly where Watson first said he was injured, but he says shoulder one time, then later says leg, then later says "one of my limbs." This argument is akin to how many times Watson has been married (and which was the third continent) and this is an interesting way to get the point across. John was shot in the shoulder and his leg injury was, at least partly, psychosomatic. Sherlock cures the leg in the first episode and we never do see John nursing his shoulder. Watson is laid up a number of times by the cold damp in the cannon, which makes me think it's more the change in surgical techniques than lack of injury. I do wonder if John took ill with a fever as well. That's something that happened in cannon but they don't mention.
