Well John doesn't want to play Cluedo with Sherlock again so I was imaging what happened the first time. This is what I came up with.
Cluedo
"SHERLOCK STOP SHOOTING THE WALL!"
"BUT I'M BOOOORED!" Sherlock moaned. John sighed.
"Well there must be something we can do...a board game perhaps?"
"It has to be an interesting one then."" John went to search in cupboards for any games he could find. He found Four in a Row, Tiddlywinks, Game of Life, Monopoly and Cluedo. He decided the only one that would possibly entertain Sherlock was Cluedo. He took it into the sitting room and laid it out on a table.
"Sherlock! I've got a game!"
"Is it interesting?"
"Come and see." Sherlock came and sat down at the table.
"Hmm might be interesting..." They started to play.
An hour later.
"I KNOW WHO DID IT!"
"Ok Sherlock. No need to shout."
"But you needed to know."
"I am just across the table from you. Anyway who did it?"
"Professor Plum killed himself in-"
"What? No Sherlock he didn't kill himself!"
"Well that is what happened so-"
"No it isn't. Wait let me check in the rules." John flicked through the rules. "See it isn't in here!"
"I might have ripped that page out last time I played..."
"I'm not even going to ask what happened last time. Because you ripped out that page it means we can't check and therefore it means it isn't in the rules."
"No it doesn't!" Sherlock whined.
"Look the victim cannot have committed suicide."
"People commit suicide in real life. And suicide is much more interesting to investigate than a murder."
"Yes but we aren't investigating anything! We are playing a board game!"
"NO!" Sherlock cried. He wiped everything off the board in anger.
"That isn't going to help matters Sherlock." Sherlock pushed the board on to the floor. As John picked it up Sherlock threw a knife at it pinning the board to the wall.
"What was that for?"
"I don't like this game anymore!"
"Did you like it in the first place?"
"NO!"
"I'm going out for some air. I want the board away when I get back. Ok?"
Sherlock ignored him. He had curled up and was going into major sulk mode. John sighed and went for a walk.
