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 of the office trying awful hard to keep a straight face.
Suspecting some mischief, I asked her how the plastic got into the drive.
"Oh, you mean the condom!"
"Condom?"
"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 could be)
"Does that mean I don't have to stroke it ten times or blow on it either?"

Customer: "My computer crashed!"
Tech Support: "It crashed?"
Customer: "Yeah, it won't let me play my game."
Tech Support: "All right, hit Control-Alt-Delete to reboot."
Customer: "No, it didn't crash -- it crashed."
Tech Support: "Huh?"
Customer: "I crashed my game. That's what I said before. I crashed my spaceship and now it doesn't work."
Tech Support: "Click on 'File,' then 'New Game.'"
Customer: [pause] "Wow! How'd you learn how to do that?"

Mouse Balls

I don't know how they wrote this with a straight face. This apparently was a REAL memo sent at a computer company to its employees in all seriousness. It went to all field engineers about a computer peripheral problem. The author of this memo was quite serious. The engineers rolled on the floor, laughing.

"Mouse Balls"

Mouse balls are now available as FRU (Field Replacement Unit). Therefore, if a mouse fails to operate or should it perform erratically, it may need a ball replacement. Because of the delicate nature of this procedure, replacement of mouse balls should only be attempted by properly trained personnel. Before proceeding, determine the type of mouse balls by examining the underside of the mouse. Domestic balls will be larger and harder than foreign balls. Ball removal procedures differ depending upon the manufacturer of the mouse. Foreign balls can be replaced using the pop-off method. Domestic balls are replaced by using the twist-off method. Mouse balls are not usually static sensitive. However, excessive handling can result in sudden discharge. Upon completion of ball replacement, the mouse may be used immediately. It is recommended that each replacer (sic) have a pair of spare balls for maintaining optimum customer satisfaction. Any customer missing his balls should suspect local personnel of removing these necessary items."
