Yes it is quite funny when Microsoft scammers call saying you have a problem with your Windows computer and you go along with them until they ask you to click on the start button on the bottom left of the screen and say I cant find that as I am running Ubuntu and the start button is on the top right of the screen. They hang up fast then. But seriously though as Athlonite said it is better not to have your number listed in the phonebook. I changed my phone number and have not listed it after the last telemarketer rung me and I have not had a telemarketer or scam call since and that was about 4 or 5 years ago.
