I somehow managed to get my Desktop folder into the Trash. I've been using Macintoshes since 1988 and that has never happened. I haven't even put much in the trash in the last day or so. Bizarre.
Well, if anyone else ever has that happen, just log out and log back in and you'll have a new Desktop file - and then just drag everything from the trashed one to the new one and you're good to go again.
