Having an MRI is one of them.

I had my MRI this afternoon. I'm serious, if you've had one you know what I'm talking about--it's the most boring thing on the face of the planet. I'm dead serious. I couldn't fall asleep because the machine was so loud. And so I did multiplication tables in my head for a little while, before moving on to going over the Periodic table of elements. I kid you not. I was bored enough to do school-related stuff. I then started signing '99 bottles of beer on the wall' to myself, I got to 89 before I started to feel like a complete moron. I then counted all the ceiling tiles I could see. There's 26, by the way. I then studied the wallpaper, it had interesting patterns of swirlies in it, so I could see pictures in it. I saw a starfish, and unhappy face, and Wiz Pig from Diddy Kong Racing. I then started hearing repetative words coming out of the hum on the machine. So it sounded like it was saying 'panda, panda, panda, panda' over, and over, and over again. By the time this was over I was completely insane. My parents laughed at me when I told them all this; but good Lord! I was about to loose my mind!! And I won't get the results back for another week. Oh well.
