can you hear me now?

My dad is not a fan of technology. He still has no idea how to work his VCR. Yes, that's VCR--you can forget about the DVD player! He recently got a cell phone. Now, when he's out and about, we're all subjected to random "Can you hear me now?" phone calls. Then, when he gets home, he calls from his home phone to make sure you really could hear him. . .I suppose that voice he hears on the other end could be someone from the cell phone company or government convincing you that cell phones really work. . .[sigh] Parents. 'nuff said.
