The telemarketer who is laughing at you took a wrong turn in life. See while you were out making your life better they can only work a job that their fat ugly slug like appearance won't be a distraction.
Now it's very important that you do exactly as I say. When these pathetic losers call you, remember time is money, the more time of theirs you waste, the less profitable they are. Your job is to keep them on the line as long as possible then when you can go no more laugh in their ear and cream telemarketer rodeo, the one who keeps them on the line the longest wins. (my personal best is 19 minutes and 32 seconds, he was extremely upset which made me laugh even more.
