Fandom is also fan art, sometimes made of scenes juxtaposed with other dialog (helLO, Trek!) like this parody poster, sometimes with a snappy caption, like a thank-you card from Mike Stamford to Sherlock fandom...
Alert for season 2 spoilers.
Then there's the punchline that didn't happen in Baskerville. Or what most of us were thinking about Sherlock's unusual outfit in Scandal!
The dialog that DID happen ("Hostage!") in Reichenbach. Or dialog added to something else entirely.
If Bilbo had been there at the tea party instead of off filming!
Bonus STID Trek art of Spock and the villain.
