Third Intergalactic Peace Conference

The Third Intergalactic Peace Conference was a peace conference which the Doctor was to attend, according to his third incarnation, before he was captured en route to the conference, by a group of Medusoids. They used several mind probes on him in an attempt to find out where he was going. The Doctor managed to short out every one of the Medusoids' probes (by truthfully telling them, "I'm on my way to meet a giant rabbit, a Pink Elephant and a purple horse with yellow spots."), forcing them to release him.
