Ross: [after seeing Monica and Chandler through the window] CHANDLER! I SAW WHAT YOU WERE DOING THROUGH THE WINDOW! I SAW WHAT YOU WERE DOING TO MY SISTER! NOW GET OUT HERE!
Chandler: Well, we had a great run. What was it — four, five months? That's more that most people have in a lifetime. So bye, take care, buh-bye then. [kisses Monica and gets ready to jump out the window]
Monica: Where are you going?
Chandler: Oh, I'm going on the lam.
Monica: Do you really think the best reason to get married is because you're sorry?
Chandler: Well, no, the best reason to get married is pregnancy. Sorry's about fourth, behind being ready and actually wanting to get married.
