My DH is a computer guru - geek - whatever you want to call them. He had such fun with those guys. When they asked him about our computer, he would ask them "which one?" They never really figured out what he meant. We have about 12 computers in our house. My DH will keep then talking until they get fed up with him having an answer for them, whatever they ask. One time the guy was so upset he said some 4 letter words and hung up. Now we have caller ID which reduces those calls immensily.
