When the Doctor's around, tomorrow is yesterday, yesterday is tomorrow and 18th century France is in your fireplace. Confused yet? Watch the Timey-Wimey of Doctor Who. You've already seen it in the future.

While a voiceover has the Doctor talking to the Ponds on the phone, he is shown with a surfboard, running away from Sontarans. When he is trapped, he throws the surfboard down into some lava in order to escape. He also recalls the memory of meeting Mata Hari in a Paris hotel room and recording some backing vocals for a rap song. He says that he should visit them any day, if he can get the TARDIS to fly there properly. The Ponds are then shown; Rory deletes the Doctor's phone message and they have a toast to the Doctor.
