Quote from Ross in The One with the Monkey
Ross: Party! Monica: That thing is not coming in here! Ross: That thing? This is how you greet guests? Let me ask you something, if I showed up here with my new girlfriend, she wouldn't be welcome in your home? Monica: I'm thinking your new girlfriend wouldn't urinate on my coffee table. Ross: He was more embarrassed about that than anyone. Okay? And for him to have the courage to walk back in here Iike nothing happened- Monica: All right. All right. Just keep him away from me.
