Computer Diving


(This is not a joke.) A man bought a computer and went diving. Two days later, he brought it back stating it was defective. Since we also could not make the computer function, we replaced it on the spot. A couple of days later, the computer woke up and functioned as designed.

The diver had not read the instructions, input wrong information and thus violated the unit. For safety and as designed, the computer shut down for 48 hrs and his diving for the weekend was over.
