Quote from Rachel in The One with the Ball
Rachel: You guys, this cat is nothing like my grandmother's cat. It's not sweet. It's not cute. I even dragged that little string along the ground, and it just flipped out and scratched the hell out of me. And I swear, I know this sounds crazy, but every time this cat hisses at me I know it's saying, "Rachel!" Ross: Doesn't sound as crazy as paying $1000 for a cat. Monica: You paid $1000 for a cat when you owe me $300? Rachel: Well ... I was gonna let you play with it.
