SUMMARY:  An advertising agency in the mid-1960s is in trouble - they've had no new clients in eight months. There's also friction between secretary Mary KcKilligan and her father, agency head Richard McKilligan. He doesn't like her new beatnik boyfriend, Bobby Zimmerman. A potential client, stage and screen star Sir Robert Llewellyn, arrives for a meeting. He wants a new gimmick to attract a modern audience. The answer comes from Bobby, who has invented a button that makes a "boing" sound. He calls it a "boner." Llewellyn is thrilled, but Richard is not pleased.
