OK the song is about cautioning a woman who wants to leave her lover and it seems like they've been in a long time relationship about the evils of the world and how it's not such a friendly and warm place and hoping that she'll be fine but then the guy sounds concerned that she won't be. It's a sad and serious song. And then he wishes her a lot of nice things to wear? If that's not funny and doesn't make you laugh then I don't know what to tell you. Within the context of the rest of the song I think it's kind of silly. :D
