A few years back, I was working on a project at a busy, chaotic institution in (where better for busy and chaotic?) New York.

A female staffer called in a panic. She had hit a keystroke in Excel and a cell in the spreadsheet nearly exploded with text along the lines of "Hey, if we could hook up I'd really be interested in <INSERT VERY DETAILED SEXUAL ACTIVITIES HERE> and, man, I could really dig it if I could <INSERT EVEN MORE DETAILED FUN HERE> and <SO ON AND SO ON>...

We were concerned. We thought: Virus? Back Orifice? Other exploit??

After 2 hours the verdict: PCs in this department had been shuffled around quite a bit and this woman inherited a particular Gateway "smart" keyboard from a gent across the hall who had apparently inadverdently programmed one of the function key combinations with a snippet of his ICQ.
