Reasons why Richard Scarry’s third little pig is quite obviously the Doctor…
1. He has a thing for hats, jackets and bow ties.
2. He has an encounter with the Bad Wolf.
3. His mother is clearly the second Romana.
4. He escapes from the aforementioned Bad Wolf by hiding inside a large, roughly conical object.
5. Finally, he lives in a house that is apparently much bigger on the inside than it is on the outside.
