I will get ideas like this out of the blue, but I think that this one is entirely doable. Here is the premise. First you go down to your nearest tech store and buy a phone with prepaid minutes on it, the cheapest will do. Make sure it is active and it has a working number and such. Then you sign up for the service at brring*com, and use the number that you have for the cell phone. Get this all situated and have it active. Now, the best part. Sign up for any and every free phone offer you can find so that the telemarketers are ringing you nonstop. With enough effort you can easily hit 15-30 calls a day since I know people who get them without even wanting them. Set it/them on silent and let the money flow in.
