Grab a few friends via online chat or something and observe: One time I got a call from a marketer after repeatedly telling the same company to stop calling. I quickly called a few friends; one on skype and two next door. We prepped while I stalled the caller. Here is the scene: "Sure, tell me what it does." (Some silly cooking thing) She proceeds to explain what it does. Suddenly a friend breaks some plywood with a hammer (sound of door smashing) and begins yelling. My other friend grabbed his phone with a gun simulator, and hooked it into my speaker system. "Bullets" went flying. I started yelling, the woman on the other end began shouting, and the scene went on. A fully played out home invasion and murder later. The woman was still yelling, then hung up. Within 45 minutes, cops showed up to the house to us laughing inside. They were mad at the false alarm, but when I showed them my phone and the [b]25 calls from the company in 4 days[/b], they decided it was actually funny. Lol, they even said the audio was very convincing, and they left. 2 days later, I received a formal apology from the company's CEO and $25 for the trouble.
