When robot factories go to war
There's one more thing I need to tell you, but we need to do it where there are no electronic listening devices.
Is this something you don't want the robots to know?
Yes. It's dangerous to them. Literally causes brain damage.
Used incautiously, what I'm about to tell you could lobotomize nearly every robot in the solar system.
This might be a good time to mention that I'm really bad at keeping secrets.
