1213

On 13th January 1213 — or the 13th day of the 13th year of the 13th century — the Tenth Doctor and Rose Tyler met some Triskaidekaphobes on the 13th moon of the 13th planet in the 13th galaxy. They help these highly unlucky individuals to overcome their run of bad luck by destroying Bob Kreesus' luck machine. (DWAM: Triskaidekaphobia)
