Example One:
The Doctor Talks to Himself Now, for a sane response to being prank called by the Doctor, please see Slyvester McCoy. For total awesomeness, see this recording fof John Culshaw calling Tom Baker. Tom Baker is more awesome than all of us.
Example Two:
Tom Baker Talks to Himself
Highlight, John Culshaw and Tom Baker saying random words with the "rich fruitiness of [their] sumptuous tone".
I'm suspecting that John Culshaw is also probably more awesome than us. But only when he's Tom Baker. Such is the awesome of Tom Baker that it just cannot be contained by one person.
