'"Imagine," Galsworthy continued, "that you know your buddy Kyle is in an important meeting and you know that he keeps his phone in his pocket. You can deliver a digital punch right to his thigh. He jumps out of his seat during the meeting and . . . it's hilarious!" Galsworthy was so tickled by this description of events that he was lost in fits of laughter on the other side of the phone. To me, this service is childish and, well, kind of stupid.'"
