You awake in a very bright room. Trying to adjust to the light, you go to wipe your eyes but realize you are handcuffed. Looking around you now notice you appear to be in an interrogation room.
"How did I get here?" you wonder. Suddenly a large man bursts in through what must be a door behind you. He slams a packet on the table and many photos slide out. Some look recent, some much, much older. All of them appear to be of some important moment. One pictures the building of the Statue of Liberty, another a pyramid. All of them, however contain the same man, but he seems to be the same age on all of them.
"Start talking."
"What is there to talk about?"
"Don't toy with me," the man grimly complains, "that's very obviously you. How are you in all of these?"
"Photoshop?" you offer, but he laughs. How are you supposed to explain to him who you are?
"Okay, okay," you finally offer into the silence, "I'm... well I'm the Doctor."
"Doctor?" he scoffs, "Doctor who?"
"That's it," you apologize, "just the Doctor. I'm from the planet Gallifrey... I'm 903 years old."
The man seems cross. "The planet Gallifrey? That's not even a real planet! And you aren't a day over 30! If you are going to lie, you could at least make it believable. You didn't even try!"
"I'm not kidding!" I shoot back, "I really am from space. I'm a Time Lord. Last one actually. Now..." A buzzing noise occurs suddenly, and I stand up, free of the handcuffs, pointing my sonic screwdriver at the man.
"Wha- how- bu- how, how did you just do that? Who are you?"
"I am the Doctor, the last of the Time Lords from the planet Gallifrey. I'm 903 and this, is Rose Tyler." Suddenly the door slams open and pretty blonde woman flies in. She runs in front of me, grabs the photos, and runs out, shouting "come on!!!" as she leaves.
"Never underestimate the Doctor. Now, allons-y!"
