I told her I'd take a look and proceeded over to her machine, where I found shredded up clear plastic Baggie-like stuff hanging out of her 3.5" floppy drive. While I spent the next 20 minutes getting out her disk and digging out the plastic, I noticed two guys, John and Dave, in the hall trying awfully hard to keep straight faces. Suspecting some mischief, I asked her how the plastic got into the drive.
"Oh, you mean the condom!", she said.
"Condom???", I asked.
"Yes, John & Dave over there told me to always put a condom on my disk before inserting it, to prevent catching viruses."
By this point, John & Dave were roaring, and it was all I could do to keep from joining them. The "condom" turned out to be a standard 3.5" plastic sleeve. I delicately explained to her that a practical joke had been played, and she shouldn't do that anymore, when she asked (as serious as one could be):
"Does that mean I don't have to stroke it ten times or blow on it either???"
