A/N: this story is going to be a combined one by me and doctorcoffeegirl, my newly discovered fanfic friend :) lol. Anyway, I'm going to be writing as Sherlock Holmes, pulling the first prank on Watson, and she will be writing as John Watson and doing his retaliation. This will be an on going thing and I'm sure we'll try to update regularly :D also, this story will be posted on her profile (exactly the same). We won't know what each other's prank will be so there is no planning ahead. It's kinda like us actually having a prank war :) but using Holmes and Watson to carry them out :)

It's set in the 1800s and is based on the RDJ and JL version

Anyway, enough from me, on with the story! :)

Holmes' POV

"Holmes!" Watson shouted, I sighed.

"Yes my dear Watson?" I replied.

"What have you done to Gladstone this time?"

"Well, I was simply testing-"

"Stop testing on my dog!" he interrupted.

"One, its rude to interrupt and two, our dog" I grinned behind my book.

"Holmes, I swear, one day you're going to take it too far and kill the poor animal!" he sighed and slumped into his chair.

"Not at all Watson, I know how much is safe for him to consume. Besides, who else could I possibly test it on?..." a thought struck me "Watson-"

"No"

"Beg pardon?"

"I said 'no'"

"I didn't even-"

"The answer will still be no" he interrupted. Again.

"Watson, if you let me finish a sentence I-"

"No Holmes. You're not testing anything on me… or Mrs Hudson"

"How did you even know I was going to ask-"

"I just did"

"Watson, if you interrupt me agai-"

"Just stop testing stuff on my dog" he ordered and picked up the newspaper.

"Our dog" I muttered and decided that Watson would make an interesting test subject to see the reactions of an ex soldier when surprised upon awakening.

So, I left him to his newspaper and went about coming up with a plan.

Hmm… morning. Watson wakes up at roughly 8 each morning.

I wonder if I still have that hand from my last case.

Without a word to Watson, I rose from my chair and made my way to my bedroom door.

"How long will he be out for Holmes?" Watson sighed.

"Roughly another hour or so" I replied and went into my room, closing the door, I began the search.

Hmm… did I leave it in a box or did I take it out?

I peaked under my bed and saw a load of boxes. This could take a while…

After an hour of searching, I found the hand. Along with some dead cockroaches, the tarantula that I had stored in honey and a load of string. Perfect I smiled.

I checked my pocket watch, '10.37' Watson should be retiring soon and I can begin work on the first stage of my plan.

At exactly 11 o'clock, Watson called to let me know he was off to bed.

Once I was sure he was safely in his room, I set up base in the living room.

First, I removed the old tarantula from the honey and gave her a good clean. I then attached the string to her abdomen and made sure there was enough string to reach from the ceiling to just above Watson's nose. This whole process took me 37 minutes; the honey was rather hard to get off.

I placed everything into a box and waited. After 23 minutes I went upstairs to stand outside Watson's bedroom. Once I could safely confirm his breathing was regular, I crept in and began my preparations. I hung the spider from the ceiling and made sure it was only about 15 cm away from his face. This was extremely difficult seeing as he kept stirring so I had to remain completely still until I could safely say he was still sleeping.

I placed a few cockroaches on his pillow, one in his drink and one in each of his slippers. Glancing at my work and checking it was all to my liking, which is was, I placed the hand so that it was on the pillow next to his and tiptoed from the room. With one last smirk, I left and retired to my own room.

I awoke at 7 and so I decided that I would go and sneak back into his room so that I could watch the event unfold. He was currently led on his side, facing the hand and cockroaches.

Once I had placed myself in the corner, hidden by a chair, I waited.

He began to stir at exactly 7.55. At 7.57 he opened his eyes.

As soon as he saw the hand, he screamed (not very manly either) and rolled over to face up, where he came face to face with…lets call her Betsy… he made a startled yelp rolled over again where he fell to a twisted heap of sheets on the floor.

Somehow, remaining completely straight faced, I rose from my hiding place, holding a pen to the page of a note pad and read aloud as I wrote, "subject reacted in a scared manner. Did not resort to violence, just screamed and rolled away. Further tests may be necessary"

I was near the door by the time I had finished writing and just managed to duck through it as Watson hurled a book at me accompanied with a very loud "Holmes!"

"Subject reacted violently to observer. Observer would like to perform another experiment at a later date" I stated, loud enough for him to hear, as I stood outside his now closed door.

I dashed into my room and promptly burst out laughing.

"Well Watson" I said to the empty room, "that's what you get when you ban me from experimenting on our dog" I smirked.

A/N: hope you enjoyed it. I was a bit stuck and didn't really know how to start, but I hope this was ok :) the next chapter will be written by doctorcoffeegirl. Thanks for reading. Let me know what you thought.
