Even though we are on the do-not-call list we still get calls throughout the day. Always the same, you pick up and there is a pause while the call connects to a live body. I've given up answering them as they always hang up when I tell them we are on the do-not-call list. The other day I was home at the same time my 18YO daughter was. The phone rang and she picked it up but did not hang up right away. About 30 seconds after she picked it up I hear giving the caller the Bronx cheer at alternating speeds & tones, staccato, continuous, high, & low, a real fartopalooza. I started laughing and asked her what she was doing? She told me she always does that when those calls come in. She said she used to yell at them but they hang up as soon as you raise your voice. For some reason with this technique they stay on and try to talk and when they do, she does that. Sometimes they get really mad and yell at her and then, she hangs up on them. I approve of this method.
