- “Thanks, Rick. I'll try to remember to shut off the Brainalyzer. Actually, I think it shuts off automatically when your brain is liquid. Don't know, don't care.”
- —Cornvelious Daniel to Rick Sanchez[src]
In addition to its tendency to liquify the brains of its subjects in the event of a prolonged session, the Series 9000 appears to have technical limitations on what its 'actors' can do. While the actors in at least most Brainalyzer simulations will follow even the most ridiculous and impossible demands made by the subject (evidenced by Rick's lack of surprise when instructing the simulated Jerry to fold himself), the Series 9000's actors can be distinctly identified by their inability to fold themselves more than six times.
