My favourite (told to me, so it may easily be urban myth) was of a GP who called a computer help line after buying a modem. He was confused as to how he got onto the internet with it. It soon became obvious that he didn't have a computer, just the modem.
The other classic is "My coffee-cup holder has broken!" of course.
