I fixed the computer of one of the girls in this dorm that way. (I can't think of her name. Note that such namenesia is nothing out of the ordinary for me.) She flagged me down in the hall at Wohl Center and told me about her computer problem: She couldn't log in, and sometimes it wouldn't even boot. She initially suspected a virus, but I figured out otherwise...
"Oh, and the caps-lock is upside-down."

"Shut up. No, I mean that when typing my name, it types caps with caps-lock off and types lowercase with caps-lock on."
"Oh. You have a stuck SHIFT key."
