Most of this is s2, sometimes mixed with s1 -- so here's the spoiler zone:
Sherlock and John -- friends forever photoset/poster.
Sherlocked: "Everybody after watching Sherlock..." Beautiful ethereal Sherlock. A different variation on that same theme.
Trek spoiler zone. Not very spoilery nor funny, but it is 2013 Trek: AngryBatch from STID. "Shall we begin?"
Cabin Pressure spoilers if you haven't heard this eps (as I have not): CabinLock: a mashup of Sherlock gifs with Cabin Pressure. Like you do.
