You had always thought of people as playthings. This is not a judgment. You always take good care of your toys. But you're going to have to let this one go.

Here's a
link to the episode on Hulu, but don't watch it unless you've seen Season 1, especially "Needs."
Geek trivia side note: the episode was directed by Jonathan Frakes, aka Will Riker from ST:TNG.
