Scales of Injustice
Last of the Gaderene
Speed of Flight
Another very difficult choice - this time because they're all pretty good. In fact, I'd go so far as to say that Jon Pertwee probably had less dud stories than any other classic series doctor.
I know I've left some classics off here, like the Daemons but that's because this list is about my personal choice - not what is classic and what is not. In my case, Planet of the Spiders holds a very special meaning for me because it was the very first Doctor Who story I ever saw - and it's the direct cause of my arachnophobia. I was only four at the time.
