I hope someone tries to phone witness to me.
First of all, I will ask if the person is a pioneer. If so, bonus! I will let him do his spiel and tape record him offering me literature for a "donation". Then I will forward the tape to the FCC with a complaint that the person is telemarketing despite my listing on the Do Not Call List. When the dubs try to say they are not telemarketing, I will point out that they are selling literature at a higher price than they paid for it--that's marketing.
