I passed my Microsoft Powerpoint exam, and one of the projects I did for it was "The Ten Faces of Doctor Who", back in the days when it was ten.
The examiners were highly impressed with my work.
I was also a regular on tombaker.tv when that was still around.
With the Time Lords now destroyed, the Doc can now regenerate as many times as he wants to, whereas back in Tom's time it was only twelve.
Who knows how many Doctors we'll see.
