Caller: “I need to report a very serious computer crime! The local university is running an illegal computer system!”

Me: “Could you please repeat that?”

Caller: “The local university is running an illegal computer system! They’ve hacked it!”

Me: “How could you tell they’d hacked it?”

Caller: “Well, when it booted, it didn’t say Windows or Microsoft or anything! It said something about Deviant Linux, I think, and the main screen looked nothing like my good, legal Windows screen at home! I think they hacked that, too!”

Me: “Do you mean Debian Linux?”

Caller: “Yes, that! Is it some sort of computer mafia or something?”

Me: “Uh, no, it’s just a different operating system. Nothing to worry about.”

Caller: “But it’s illegal! It’s not Microsoft, not even Windows! They’re on a normal Microsoft computer, so they’re breaking the law! I think they stole my identity when I came in the building! I’m calling the FBI!” *hangs up*
