The Doctor : What is the matter with you?

Peri : Well, since we left Telos, you've caused three electrical fires, a total power failure, and a near collision with a storm of asteroids.

The Doctor : Oh, pffft!

Peri : Not only that, you twice managed to get yourself lost in the TARDIS corridors, wiped the memory of the flight computer and jettisoned three quarters of the storage hold. You even managed to burn dinner last night.
