I sat down to enter doctors' orders into the computer yesterday only to find my computer screen upside down. I kind of tilted my head and tried to get my barrings, then heard snickering the next pod over. Our unit secretary (tied with one of the PCTs for the ultimate prankster) was peaking around the corner laughing at me. We spent the rest of the day laughing at doctors' reactions to the upside down screens as they sat down to check patients' charts. Our favorite was the one who turned the whole computer upside down. We're so lucky it didn't break!
P.S. In case you need this kind of entertainment where you work, just press control-alt-down arrow and see how confused your co-workers get. (and sorry--it only works on dell)
