4 April

On Easter Sunday, 4 April 2009, Lady Christina de Souza stole the Cup of Athelstan from the International Gallery and made her getaway on a number 200 London bus, only to be unexpectedly transported to the planet of San Helios, by means of a wormhole, in the company of the Tenth Doctor. Eventually, the Doctor flew the damaged bus back through the wormhole, and Christina made her escape from the police on the now-flying bus. (TV: Planet of the Dead)

Who cares? I sure don't.
