With nine people in the house, Mike gets frustrated when he can never get any time on the phone for himself. He decides to install a second phone line, but that only makes the problem worse. Thanks to one of Alice's ideas, Mike decides to install a pay phone in the family room. The plan works ... until Mike needs to use the phone one day to set up an appointment with a hard-to-please, heavily scrutinizing developer ... and when the phone company cuts the call off and Mike doesn't have a dime, the developer isn't too amused at all. But in the end, the pay phone proves its worth, both for Mike's blood pressure and securing a multi-million-dollar contract for Mike's firm.
