Quote from Ross in The One with the Fake Monica
Ross: Where exactly is your zoo? Dr. Baldharar: Well, it's technically not a zoo, per se. It's more of an interactive wildlife experience. Let me ask you some questions about Marcel. Does he fight with other animals? Ross: No, no. He's very docile. Dr. Baldharar: Even if he were cornered? Ross: Well, I don't know. Why? Dr. Baldharar: How is he at handling small objects? Ross: He can hold a banana, if that's what you mean. Dr. Baldharar: What about a hammer or a small blade? Ross: Why would he need a blade? Dr. Baldharar: If he's up against an animal with horns you got to give him something. Otherwise, it's just cruel.
