Don't Blink!
The Meeping Angel and the Doctor.
(You can tell it's the Doctor as they have a sonic screwdriver and are wearing a fez.)
The Doctor's glasses are the latest tech from Muppet Labs and are guaranteed not to allow anyone to see you blink.
However as the glasses are from Muppet Labs, the Doctor should probably run.
Alas I don't know who came up with the idea of the Meeping Angel, I think I first saw it as a cosplay picture.
To that person I say "Brilliant idea!"

Another note, if you made it this far down in this post, I've added a link in the post above to an animation of the next Doctor acquiring the fez from Porg O'Rosso.
