Steve: So how was it with Jeannie?

The brain of the human operator. Cybernetic devices depend on the hardware (the physical pieces of the device), the software (the programmed instructions) and the jellyware (the person who pushes the buttons and his decision-making.)

When some resigns or retires from a job, they are on "eternity leave". This can also refer to someone who has passed away, especially someone who worked somewhere for a long time, retired/resigned, then passed away later.
Oh I'm sorry, you didn't know that Kelly is on eternity leave? She resigned and moved to Hawaii!
With regrets I would like to inform you that my boss is officially on eternity leave. I will never see or hear them again. Ever.
