Quote from Ross in The One with the Free Porn
Ross: She doesn't know which one of us she wants, me or this "Colin" guy. Monica: This isn't how it's supposed to go. There can't be another guy. Of course, there's another guy! This is even more perfect. Now you have to prove your love. Ross: I'm not proving anything. Okay. I'm done listening to you. If I hadn't let you talk me into going to the airport in the first place, I wouldn't have put my fist through the wall. Chandler: You put your fist through a wall? Ross: No, I missed and hit the door. But it opened really hard.
