Welcome to this week's Doctor Who's Day roundup, a tractor beam trawl of memes, fan art and general Whovian stuff and nonsense over the past week on the internet.

And speaking of memes, we start this week with the meme-iest Doctor Who story thus far. The Doctor and Bill met the Vardy and the Emojibots in "Smile" on Saturday, and naturally fandom reacted gloriously.

Here's how Peter Capaldi and Pearl Mackie introduced the episode:
