How many times have you been at a place like the airport and thought someone was listening to that conversation you were having? Well
MediocreFilms pranked people by not only listening to their calls, but responding to what they were saying to the person on the other line. How will they react? You just have to watch to find out. And wonder what you would do if you were the caller and a stranger was responding to everything you were saying. I am not sure what I would do.
