It was odd. I was turning, it was pretty low-speed, and the bike just seemed to fall. I wasn't doing anything particularly bad. In fact, in retrospect I'm not at all sure why it happened. Maybe my tires are more worn than I'd realized. I can't think of any other reason a random slowish right turn would turn into a skid-off-the-road.
The skinned knee looks gruesome, but is bleeding barely at all. There's a big black patch in the center which I'd assumed involved asphalt, but it's not bleeding, it's not doing much anything, and the black doesn't quickly wash off, so maybe it's ground-in grime or something.
The muffler was hot enough that the leading edge of it melted up a chunk of road paint. Yeah. Like, it was all gooey. I assume that happened while the bike was on the ground and not while it was falling, because it wasn't gouged -- it was just kinda melted on.
