We just discussed how it was a myth. They wake concussion patients up every few hours when they're sleeping if they can't directly measure their brain activity to ensure that they haven't fallen into a coma.
Yeah, they did that to me when I was a kid admitted overnight for possible concussion. They knew I was okay because I was getting PISSED that they kept waking me up every hour.
How I wound up there:
As a kid, I loved Looney Tunes (hell, I still do). And after getting done with my shower and my pajamas on for the night, I would sometimes pretend to be Speedy Gonzalez and race around the house yelling "Arriba! Arriba! Andele! Andele!"
This one night, I did so and ran into the kitchen not knowing that my grandfather had just mopped and waxed the linoleum floor.
"Arriba! ArribaaaaAAAAAHHHHHH!!!!"
The funny part is that I kinda froze and managed to keep standing up as I slid at high speed towards the counter. Had I been alone, I would have caught myself on the counter and been okay. But my grandfather turned around, saw me careening terrified across the floor like a deer in the headlights on ice, and tried to help by swinging out his arm to catch me. Unfortunately for me, he misjudged my height by several inches and clotheslined me with a right hook that would have made a professional wrestler weep. My feet went flying out from under me, and I fell back hard on my head. The floor was a thin layer of linoleum over a thin layer of hardwood over a concrete slab.
I got a couple of aspirin and some profuse apologies and went to bed. Middle of the night, I woke up with an incredible throbbing in my head, like someone was stabbing me in the ear with a knife made out of pain. Given the way I was screaming, we rushed me into the hospital. Turns out, I had hit my head hard enough that it dislodged my eardrum slightly, tearing the skin around the edge of it and allowing a bit of bleeding inside the ear. They kept me overnight for observation and gave me some meds for the pain. It was fun at first (hey, the bed has a remote control!!) but I quickly got sick of being woken up every hour and asked my name and if I knew where I was.
I also stuck my tongue in a light socket once because, hey....light socket. I think I was fascinated with the taste of metal at the time (i was like 4 or 5). The stupid part was when I wondered "I wonder if it tastes different with the power on". >_<
The answer is yes, yes it does. It tastes like BZAAAAAAAAAAP--
