I got tangled in my pants/jeans one night undressing and fell over and wasn't able to catch myself, "scraped" my nose on the rug (and then kept making it worse during work by pushing my glasses up my nose). I made the mistake of saying I'd been out to dinner/drinking ("date night") so all my coworkers decided I'd been drunk and that's why I fell over and got my "rug burn." They spread it through the company ("small" family company and I'd been there a long time, only about 40 people) and are still laughing at me and I've been retired a year and a half :-)
