Quote from Phoebe in The One with Phoebe's Ex-Partner
Phoebe: [playing guitar and singing] Smelly cat, smelly cat, What are they feeding you? Smelly cat, smelly cat, It's not your fault. Leslie: That's great. You know, you could totally sell this. It'd be perfect for, like, a kitty-litter campaign. Phoebe: A jingle? No, no, no, no. Leslie: Why not? You'd make a ton of money. Phoebe: If I was in this for the money, I'd be a millionaire by now, you know. You gotta get out of that jingle-head, sweetie.
