Why is Pakistan playing test cricket?

I can picture a scenario where Salman Butt tells his batsman, "Come soon. I'll see you before lunch!"
Right now, the Pakistani batsmen are playing shit.
I don't think there's anything else to describe their game right now.
And the funny thing is that people were after Bangladesh's throats when they would consistently lose to sides all over the world.
Pakistan is doing pretty much the same thing. In fact, they're playing worse than Bangladesh right now. It's ridiculous because James Anderson is taking 10-wicket hauls. That's just wrong.
I'd understand if Graham Swann or Graham Onions did something like that, but Anderson?
Even Broad seems to be bowling well.
For England's sake, I hope they don't take this victory as overconfidence during the Ashes. Although Australia isn't playing their best cricket, it's a home series for them and that will always work in their favour.
But Pakistan? They need a lot of work to do.
