Caught myself with a Parker 91R back when I first started DE shaving. I'd been doing it long enough that I was fairly comfortable, but I leaned closer to the mirror and bumped my elbow on something, sank the blade right into my cheek near my lip. Took a while to stop the bleeding on that one, but at least I don't have a scar from it. I figured out later that the razor had alignment issues and I binned it in favor of a Tech.
