ARTHUR I'm sorry -- did you just say you need my brain?

BENJY MOUSE Yes. To extract the question.

ARTHUR You can't have my brain. I'm using it.

FRANKY MOUSE Barely.

BENJY MOUSE We can replace it if you think it's important. An electronic brain maybe.

FRANKY MOUSE A simple one should suffice. Who would know the difference?

ARTHUR I would!

FRANKY MOUSE No, you wouldn't. We could program you not to.

Source? This is gold.
