Here’s a script (courtesy of Nighthawk) that can help you drive telemarketers crazy, if you’re so inclined.
Personally, I find it easier to a) get listed on the do-not-call registries, and b) ask any poll-takers who call (as they, charities, and politicians are the only ones who got a free pass from the government) to “take me off the list” (with that exact phrase) and then I don’t hear from them anymore.
But this is pretty funny anyway.
