Never quite knowing what part of time she is coming from, the Doctor got an even bigger surprise when River Song flies literally straight into him, after purposely ejecting herself from a space ship where she is a wanted criminal.

River wasn’t the first friend of the Doctor who had a special knack at making an entrance.

Anything for a pretty face.
