With David Tennant's tenure as the tenth Doctor ending very soon, I am putting forward 5 lessons I have learned from his reign.These are not in any partcular order:
1. Water is patient. It always wins.
2. When cornered by a Sontaran, always go for the vent in the back of the neck. A tennis ball will do the trick very well.
3. A Dalek is not a robot.
4. If someone (or something) says you need to to be upgraded, run! Just run!
5. When in doubt, invoke the Shadow Proclamation.
