'I do'

Monica: You wanted it to be a surprise.

Chandler: Oh my God. (she gets down on one knee)

Monica: Chandler, In all my life I never thought I would be so lucky.. As to fall in love with my best, my best.. (starts crying..) There's a reason why girls don't do this!

Chandler: Okay! (he too gets down on one knee) Okay! Okay! I'll do it! Oh God, I thought (he too starts crying) Wait a minute, I-I can do this.. I thought that it mattered what I said or where I said it. Then I realized the only thing that matters is that you, you make me happier than I ever thought I could be. And if you'll let me, I will spend the rest of my life trying to make you feel the same way.. (takes out the ring) Monica, will you marry me?

Monica: Yes (he puts the ring on her finger.. they hug and kiss)
