Customer: “I need a fan.”
Me: “What kind of fan?”
Customer: “A fan for where I plug my modem in.”
Me: “Do you have it with you?”
(Customer leaves and returns with the computer. A hair dryer is duct-taped to the power supply, nozzle pointing into where the fan normally sits.)
Me, dumbfounded: “Why is there a hairdryer taped to your computer?”
Customer: “Well, I have to keep it warm, or it will freeze up.”
