So I’ve mentioned the crazed / loopy / giddy / utterly silly phase that I’m in right now yes? The one that is caused by being awake from 6:15 am until about 5 am, with another four hours of staying awake to go? Plus caffeine?

Right.

So if you’re at the point where you’re as easily amused as I currently am, this video – which I have seen countless times before and which is funny on a regular day – just might make you dissolve into an absolute puddle of crying laughter, complete with hysteria-induced stomach pain.

(But you need to be a Harry Potter fan, really.)

I have watched it three times in the past half hour. I haven’t stopped laughing yet.
