[Captain Seamus]

When I was a kid, I (apparently) told my dad that I had a friend named Bob, who was a bald, invisible floating head. I don't remember it at all, but it freaked my dad out something fierce.

I guess the point here is that the main reason children are creepy is that when we look at that sticky kid shrieking on the bus, we know deep down that we used to be just like him.
