DOCTOR: The shades of night were falling fast, as through an alpine village passed, a youth, who bore midst snow and ice, a banner with a strange device. Excelsior!

PERI: Oh Doctor, stop it.

DOCTOR: I was only trying to cheer you up. One of your primitive American versemakers. Longfellow, wasn't it?

PERI: Who cares? You're making enough noise to raise the dead. I'm so tired.

DOCTOR: Courage, Peri. Just follow in my footsteps. Après nous, le deluge!
