Not the brightest bulb.

Have you ever used the bathroom in the middle of the night and, once you've finished, you flip the light switch instead of anything connected to the toilet? And then, because you realize your mistake, you try to be more alert and as you walk out the room you just stare at the light switch, not flipping it off, because you don't want to make the same mistake twice? Wild guess as to whether that happened to me early this morning
