Summary
Seven Doctors... one tricky situation. Will the First Doctor be able to save his future incarnations from a deadly game?

Plot
The first seven incarnations of the Doctor use various methods to attempt to pass a test set by the entities of Grey Space. Each Doctor fails until it falls to the First Doctor to save them all. Part of the test involves getting past a robotic guard. The Seventh Doctor deactivates the android guard by using the default password. The Sixth Doctor convinces it to deactivate by making it believe it has no purpose. The Fifth Doctor uses a Nanoware maintenance engineer card to convince the android to shut down for an inspection. The Fourth Doctor uses his scarf to wrap up the androids limbs, puts licorice whirls over its visual sensors, puts jelly babies in its audio receptors and sherbet in its processing unit. The Third Doctor had the android demonstrate its anti-matter rifle on the floor before pushing it into the hole it had created. The Second Doctor convinces the android to demonstrate its gun upon itself. The First Doctor writes PTO (please turn over) on both sides of a piece of paper and gives it to the android; this leaves the android turning the paper forever.
