Well, sir, I've seen Loch Ness but I've never seen the monster and I've talked to ghosts but they've never talked back. I've watched the Midnighters twist at the mic right next to Hank's. I've been to Manhattan, I don't know how many times, but I've never been in the empire state building.
Maybe the saddest people that I can remember being around were Elvis and Janis and Jimi.
There's a reason that we don't know everything.
