This picture is called "Ultimate Doctor Battle," alternatively titled "Give Me M'Job Back!"
Kevin explains: "Before anyone goes off on any deep-ended speculation, this is simply Matt and I GOOFING AROUND. No commentary on actual Doctor vs. Doctor popularity battles are implied. It was primarily inspired by a well known image of the Kirk/Gorn battle in a famous episode of Star Trek"
