Little Orphan Android

Synopsis

A man is watching TV and playing games. He gets a delivery: an android, which should be paid by cash on delivery. He doesn't remember ordering one, but he doesn't seem to remember anything beyond that same morning. The delivery company has binding proof that he actually did order it, and he must pay it even if it almost depletes his assets. Why has he bought it? Why he doesn't remember anything? And why does the android he just bought not seem to have any useful purpose?
