Not sure how this will come across being read and not said, but I will give it a shot. If you've already heard it, I apologise, but I hadn't, and I found it pretty funny. I hope I can type it well.
You basically have to tell it like you are telling a story that actually happened.
ME: "Hey, have you heard about that new "voice activated" radio?"
YOU: "No, I haven't, what is it?"
ME: "Well, I met this guy who has one, and he said you just speak to it and it will play whatever, like if you say ROCK, it will play a Rock song, or if you say COUNTRY, it will play a Country song."
YOU: "Well that's pretty neat!"
ME: "Yes it is, he said he was driving in his car, listening to it the other day, and some kids ran out in the road in front of him, and he yelled "FUCKING KIDS" and it started playing MICHAEL JACKSON."
