If you have never heard of cell phone crashing, this guy has gotten it down to a science. The basic premise is to annoy those people who talk so loudly on their cellphones that you can not avoid overhearing what they are saying. At first the person talking might feel it is a bit of a coincidence, but after a few minutes it becomes obvious something is not right here.
This guy first sits next to a guy talking to his buddy. When the guy begins talking about his grades, the cell phone crasher responds as if he is talking to someone on the other end of his phone. As the person talks loudly about his B+ grades, the crasher responds how that is such a good grade.
You can see how the talker does a double take and even asks the crasher if he is answering the guys questions. He repeatedly denies he is answering the questions, but then continues to do so until the person gets up and sits elsewhere.
He next sites next to a woman who is talking about what is for dinner. The crasher responds he is good with anything she makes for dinner. She then says she will at the house by 6:30, to which he replies 6:30 is perfect at my house. All the talkers respond the same way by telling the crasher that they think he is answering their questions, to which he repeatedly says he isn’t, only to continue to annoy these loud talkers until they hang up the phone.
