Because I can't seem to find a picture of this scene online, here's the epic moment we witness all the Doctor's together, right at the end of the truly epic 50th Anniversary special, the Day of the Doctor.
I print screened it off BBC I-Player. Cropped it a little on paint by getting rid of the BBC logo on the top left of the image, and the black lines at the top and bottom that made it all widescreen looking.
And just for the sake of argument, this picture is NOT a Selfie. A Selfie is when you take a photograph of yourself using a Camera, usually a Mobile Phone with a built-in Camera. I'm getting tired of the occasional commenter calling it a Selfie. It's just an epic scene to end an epic Anniversary, nothing more.
