Quote from Phoebe in The One Where Chandler Doesn't Like Dogs
Phoebe: [answers phone] Hi, Geller-Bing residence. How can I help?
Monica: Phoebe, why is there a dog in our apartment?
Phoebe: I'm sorry, who's this?
Monica: Phoebe, there's a dog sitting on my couch.
Chandler: Tell her I'm allergic, and I will sue!
Phoebe: No, there's no dog here.
Monica: Yes, there is! He's black and white and shaggy, and he's sitting next to Rachel and licking Rachel's hand.
Phoebe: Oh, my God! Where are you?
Monica: I'll be right there. [knock at the door]
Phoebe: They're here already? How are they doing this?!
