My roommate wakes me up, saying "You need to get up and go to class. You don't want to miss that Sledgehammer class."
"What?" I ask.
"You know, Sledgehammer, that video by Peter Gabriel? He's giving a class on it."
"Why," I ask, "on earth would you wake me up to tell me about that?"
"I thought you might find it interesting."

... Then I *really* wake up, and I missed my first class. Maybe this was just my unconscious mind telling me it was time to get up. WHERE it got "Sledgehammer" from, I don't know. It's a good song, but I hadn't heard it in quite some time. Aah, the mysteries of the human mind.
