Meanwhile in the TARDIS (1) - S0.E67

On her first trip in the TARDIS, Amy questions the Eleventh Doctor on how the time machine works, why it takes the shape of a police box, and whether he is an alien. The Doctor answers most of her questions, and then opens the TARDIS doors to reveal that thy are in deep space. When Amy doesn't believe what she is seeing, the Doctor pushes her though the doors.
