Martin's downfall lay partly in the fine print and partly in the fact that Erika Ashby had been in the hospital with a bad attack of influenza at the time. Buried in legal verbiage was a clause that bound Martin to five years of servitude with Summit should they pick up his option. Next week they would certainly do just that, unless justice prevailed. "I think I need a drink," Martin said unsteadily. "Or several." He glanced toward the robot. "I wonder if you'd mind getting me that bottle of Scotch from the bar over there." "But I am here to conduct an experiment in optimum ecology," said the robot. Martin closed his eyes. "Pour me a drink," he pleaded. "Please. Then put the glass in my hand, will you?

"How could I?" the robot asked. "But I've seen it done." He drew a straight line vertically upward between his invisible eyebrows, managing to look wistful. "Of course my world is perfectly functional and functionally perfect, but I can't help finding temporalizing a
