11 October

11 October was a date.
Rani Chandra began her day on 11 October 2009 with her mother walking into the force field generated by the Vorgatt defence field emitter she'd been given as protection from Sarah Jane Smith the night previous. As she, Luke Smith and Clyde Langer attended school, Sarah Jane was at the Pharos Institute getting herself a piece of the Weserbergland meteorite for Mr Smith to inspect. After inspecting it, the Xylok supercomputer and Sarah deduced that Odd Bob the Clown was actually an entity that fed on fear that arrived on Earth in that tiny meteorite.
Odd Bob, meanwhile, used balloons to hypnotise the students of Park Vale School into walking away from the school grounds and towards Spellman's Magical Museum of the Circus. Before they could all enter, though, Sarah Jane had Mr Smith call the mobile phones of all the children at once, interfering with Odd Bob's psychokinetic powers. He then kidnapped Luke, and Sarah Jane went running into the building to retrieve him. Rani, though, had a plan — she had Clyde arrive at the scene and tell jokes. The laughter killed off any fear, and Odd Bob's power became low enough such that he could be sucked back into the meteorite from which he came. Sarah locked the rock away in her attic, and finally overcame her fear of clowns. (TV: The Day of the Clown)
