True story: I heard a woman laugh somewhere in my apartment while watching TV. I was alone, or so I thought. After a brief WTF moment, I concluded that it could only have been the Echo. I spoke: “Alexa, laugh.” I then hear the exact same laughter coming from the faraway Echo Dot. And that’s how I learned that Amazon actually programmed Alexa to laugh on command, resulting in the rare chance of trolling people as a bonus.
