Oh! I forgot my stupidest injury yet. (Actually, it may at least compete with the cat one.)
I was just waking up, and my phone alarm was going off. My dresser is right next to my bed. I went to reach over to get my phone and slammed my eye into the corner of the dresser, giving myself a black eye.
In an exam I dropped my pen, bent over to pick it up and hit my face on the desk, it didn't hurt too bad but I said "ow" out of habbit. People laughed.
