One day Satan and Jesus were arguing over who was better at the computer. So God decided to have a competition where they were to create do some serious computer works, programming, word-processing, graphics, spreadsheets etc.
When the competition was about to end, a lightning storm came up unexpectedly. That caused an unexpected power outage. When light was restored, after rebooting their systems, Satan cried out, "It's gone! All my work gone!" Meanwhile Jesus simply settled down and started printing all his stuff.
Satan cried out again, "How, how is he doing that!" And an angel who was standing as an observer answers him with two words, "Jesus Saves."
