I quite enjoyed this.  It's about a boy with a broken bike encountering the Third Doctor.  The Doctor gives some advice to the boy and it is quite charming, able to effectively bring the voice and charisma of John Pertwee to life.  Katy Manning narrates and I quite enjoyed her here.  It's a simple story with some larger overtones of the Doctor on a diplomatic mission with an alien ambassador that works well on the whole - that angle really makes it feel like the boy is encountering the Doctor on a random day in his life.  It adds a wholesome feeling of this just being an incidental little event for the characters.  I quite liked this Short Trip on the whole.
