On Monday afternoon, I got a phone call that someone now probably wishes they never made. Caller ID said the call was coming from "MDU Resources," but the caller said he was calling from "the technical support center." He informed me there were "junk files" on my computer slowing it down and that he was going to connect me with a technician to help fix the problem. I was thrilled, displaying what my wife Paula felt was an inordinate amount of glee about getting the call. Over the next two hours, I subjected the scammers to such misery that Paula later told me she felt bad for them. "They probably had a quota to meet," she said sarcastically. "You probably kept them from getting four or five other people."
