Got a call from “John” speaking on behalf of the local #police soliciting for a donation. The conversation went back and forth, then I realized it was a #robocall. I was surprised at how responsive John was, but managed to knock him off his game by asking what the #airspeed #velocity was of an #unladen #swallow. The #AI began to babble about not understanding and I disappointedly ended the call. Maybe next time, John.
