Why does everyone in the DCU think Batman can handle anything?

He really can't, you know, despite what Jay Garrick might think here:

Jay, you couldn't be more wrong. Here's the proof:

With one SWOK, it's Sandy = 1, Batman = 0. At least Jay has the decency to seem a little embarrassed.

Wonder Woman is apparently no help, either. She might as well be hopping up and down crying, "Oh, what do we DO?! What do we DO?!"

And what the heck kind of sound effect is SWOK, anyway?
