Come the Mercials, ten by ten."

"That makes as much sense as the one about the liver," the lieutenant said.

"That wasn't an original thought, then?"

"Probably not. Andy may be trying me out with a few simple couplets before he throws a really hard one. I wonder if he knows he's got through to me." He laughed as the lieutenant looked at him oddly. "I don't mean he, personally. I know as well as you do he's some kind of robot."

"I see. You mean, is somebody controlling him now, or is he just reacting to a stimulus the way he was built to do?"
