If you're at school and you're not that bright or good-looking or popular or whatever, and one day you say something and someone laughs, well, you sort of grab onto it, don't you? you think, well I run funny and I've got this stupid big face and big thighs and no-one fancies me, but at least I can make people laugh. And It's such a nice feeling, making someone laugh, that maybe you get a bit reliant on it. Like, if you're not funny then you're not... anything.
