Roger is right, one could have hours of fun with this.
Well, maybe not hours exactly. That may have been a slight exaggeration. Okay, if I'm honest, five minutes tops. Unless, like me, one is desperately bored and looking for something to take the edge off a Blades induced mild weekend depression. Naah, it's back already. Plan B it is then.
Your very good health.
