This story came from two things. The first is a snippet in Time and Time Again, with Feeling! by Ala Iridia in which The Doctor is somehow teaching Class 2/3A. The second is from watching the Red Nose Day 2011 showing of Doctor Who on Youtube. This is meant to be something of a parody, at least I hope you find it funny.

As of late, Nodoka's life has been like something out of a Shonen anime. Where problems are solved by spells that could vaporize US Carrier Groups. So how has she been able to keep up with just her wits? Maybe because she's been doing it for centuries...
