"Psalm 137, folks: So the Israelites are in exile, and they're feeling kinda down about it. So what do they do? They start to sing, that's right. But it's not a happy song. They sing about how they miss Jerusalem, and how they can't forget it no matter how hard they try. And then they get really mad, because they remember how the Babylonians destroyed their city. So they sing, 'If I forget you, O Jerusalem, may my right hand forget its skill.' Brutal, folks. Brutal."
