Hey Pandas, What's The Dumbest Way You've Gotten Injured?

This happened last night. I had been sitting in my bed in a lateral position all day, and then my parents called me for dinner. I sat up and got a huge headrush, but, stupidly, I decided to keep walking out in to the hallway. As soon as I entered the hallway, I don't quite remember what happened, but I think I fainted for three seconds. In those three seconds, I fell into the corner of a wall right on my jaw. Now it hurts like heck and I can't talk normally.
