Follow that madman into his box.
From Create Your Own Story
You can't resist following him into his TARDIS. "Ha haa!" He laughs. "I knew you'd love it in here." He pulls a few levers and presses a few buttons, and the TARDIS jolts into action, smoke pouring from the control panel. The centre tube heaves painfully and the TARDIS screeches. "Close the door!" The Doctor screams. You do as you're told, running over to the wooden doors and slamming them shut. "This is bad. This is very bad." "What's wrong?" You ask helplessly. The Doctor sighs. "I need to reverse the polarity of the time vortex to get the TARDIS up and running again. But there's not enough energy. The time freeze is hurting it's circuits, we can't do anything!" "What do we need?" You ask. "Energy." The Doctor replies, his voice in a low rumbling growl. "I need some sort of energy. Human energy, anything." He pauses. "Run!" "Run where?!" You shriek. "Around! Running is kinetic energy." You both begin running in flailing circles, but it doesn't work. "Oh! I have an idea! Start screaming! That's sound energy." The Doctor squeals. You both start to yell. Nothing. "Jump." The Doctor says. "Jumping is kinetic." You begin to jump without questioning him - and you can't help but notice that your breasts are bouncing as you do so. You look over at the Doctor.
He is busy trying to fix his TARDIS and doesn't notice you. Phew.
