Dougal: The Spider Baby, Ted.
It's got the body of a spider but it's actually a Baby.
Ted: How is it a baby? Does it have a nappy on it?
Ted: Well, um does it have the head of a Baby?
Dougal: errm... No.
Ted: Well, if it looks like a spider, and it doesn't actually gurgle at you or anything; how do you know it's a baby?
Dougal: They keep it in a pram.
