If any of you out there are Doctor Who fans, this will be a hoot! In the most recent all-new episode, The Rebel Flesh (Saturday, May 21st, 2011), the Doctor and Amy set off on an adventure when the TARDIS is caught in a solar storm. I don't want to spoil it for you if you haven't seen it yet—which I highly recommend you do—but it involves doppelgangers. Anyway, I hope this funny clip brightens up your Monday! :)
