Welcome to this week’s Doctor Who’s Day roundup, a fistful of glorious Gallifreyan stuff and nonsense from the past seven days on the internet and social media.

And of course, this week, fans are aglow with the new teaser that shows Jodie Whittaker‘s Doctor and her new friends. But before we get to that, something astonishing happened in London involving the Doctor and the alien race known as the Muppets.

During their concerts at London’s O2 Arena last week — billed as The Muppets Take The O2 — Peter Davison turned up, in full Fifth Doctor costume, for a skit that ends with a hugely affectionate regeneration joke. Here’s a fan’s-eye view:

But that’s not all. The night before, David Tennant performed the same sketch. Look, he’s doing the Doctor’s voice and everything:

The audition for the new #DrWho companion went a bit wrong when the wrong Dr turned up. Timey-wimey stuff!#DavidTennant #Muppets pic.twitter.com/S7aPXjMKhc — Colin Lacey (@ol_king_col) July 13, 2018

And Kylie Minogue (a.k.a Astrid Peth) turned up too:

Which would be startling enough for any other week, but this week is special. The Season 11 teaser is here, introducing the Doctor and her new friends:

• Which was itself teased like this:

• So, say hello to Yaz and her pizza:

• Graham and his chips:

Here’s what else has been going on in space and time this week:

• Tenth Doctor fan art:

• A (newly) vibrant moment in Doctor Who history:

#DoctorWho photo colourisation time again: we’re in St Martin’s Court, London, round the back of Wyndham’s Theatre, on Friday 17th December 1965. Five lovely new Shawcraft Daleks surround an innocent phone box to publicise the stage play Curse of the Daleks which opens next week. pic.twitter.com/Woyt6qKqII — Clayton Hickman (@claytonhickman) July 16, 2018

• How to keep a secret:

• Missy looks sketchy:

• An eerie fan-made title sequence for the Twelfth Doctor:

• Cartoon Thirteen:

• There’s a crack in the sky:

Is it just us, or does this cloud formation look like a @DoctorWho_BBCA fracture in time and space? #DoctorWho pic.twitter.com/OlSUeS4ToO — colin and justin (@colinjustin) July 16, 2018

• Karen Gillan returns to modeling, sort of:

• Sonic tattoodriver:

• This is a une bonne idée:

We should let other countries make their own Doctor Who shows…. and I'd vote for Philippe Duclos to lead France's version. And his Tardis should be a Morris Column. pic.twitter.com/b5MDPhkVKq — Chris Weston #FBPE (@westonfront) July 16, 2018

• A mystical-looking Thirteen:

• The Doctor’s silver jubilee:

Seems a fair few people haven’t seen the #DoctorWho 25th anniversary press trailer before so here it is in all its 🔥8891 Royale🔥 Keff-y goodness.

‘New’ Seventh Doctor and Ace links!

Very minor explosions!

Extra Dolores Gray!

TTFN!
