I used to regularly lock my car keys in my car, especially when I had something to do.
After a long period of rain on campus, I was walking too fast like I tend to do and skipped going down a flight of steps on this hilly section. where I would have to wait for slow moving people. and just took the hill. I ended up slide surfing all the way down at much too fast rate, almost losing my balance a couple of times where I would end up coated in mud, to the bottom. I kept reasonably clean, but was a bit red faced.
I've fallen asleep in late afternoon meetings and get that swaying thing going in my chair. I've never fallen off my chair, but there is time yet.
Really, there is stuff that happens nearly every day. You should see it. I should have a reality show on what idiotic thing I'll do next.
