Got a call from this number wondering if it was possible for them to give me a "short survey" to which I replied, "no it is not" and hung up. The caller ID indicates ultra-conservative political advocacy group "Americans for Prosperity" is the source which means the "survey" is just a slanted push-poll designed to advertise for whichever Koch brother-approved candidate is being run in our area and to slam their opponent.
I don't know what they were calling about, but they filled my answering machine with a version of "When the Saints Go Marching In", and then I hear a woman say "OMG!" when she realized what happened.
