One day while returning to my desk after a routine call, a young lady flagged me down and asked for help.
"My floppy drive won't work, can you help me?"
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 her disk out and digging out the plastic, I noticed two guys in the corner trying awful hard to keep a straight face.
I asked her how the plastic got in the drive.
"Oh, you mean the condom? Yes, John & Dave over there told me to always put a condom on my disk before inserting it to prevent it from 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,
"Does that mean that I don't have to stroke it ten times or blow on it either?"
