Don't even know what to call this

This commercial has come on a few times when we're watching tv and I just enjoy how it makes my wife giggle uncontrollably--mostly because it's so darned creepy. Don't quite know how it relates to chocolate bars, or anything else for that matter.

edit: I notice for some reason this posts as wider than fits in the blog. I really must try to fix up this blog layout one of these days. If you want to see it properly, you can also go to where I posted it originally, on photobucket. I think this will work without a password:
