Quote from Joey in The One with Phoebe's Rats
Chandler: Where you going, Joe? Joey: For a walk. Chandler: You mind if I join you? Joey: Actually, I'd rather be alone. You know, I really need to organize my thoughts. Chandler: Your thoughts? Plural? Joey: All right, fine. I only have one thought. It's about the hot nanny. I gotta see her.
