In preparation for the wedding, Ross has the "big brother" talk with Chandler, telling him that if he ever hurts Monica, he'll kick Chandler's ass. This amuses everybody. Monica stresses that Rachel will forget one of her responsibilities. Joey gets a part in a World War I movie (Over There), with an actor (Richard) who teaches him that great acting means enunciation, and enunciation means you spit. The wedding rehearsal dinner is held; Chandler's parents feign civility. Chandler freaks out about becoming "the Bings" and disappears; Ross goes to look for him. The Geller parents stop by the coffee shop; Mrs. Geller takes a liking to Gunther. While Rachel and Phoebe wonder how to keep Monica from finding out Chandler is missing, Phoebe finds a positive pregnancy test in Monica's bathroom. Joey finds out he's scheduled to work the day of the wedding.
Monica: You know what? You're right, I'm sorry. Actually you were a big help tonight. Yeah, and thanks for putting my grandmother in the cab and making sure she got to the hotel safely.
Rachel: Well, of course, that is what I'm here for!
Monica: Okay. Sorry.
Rachel (to Phoebe): Uh! What grandmother?
Richard: Oh, you were awesome! And in that last speech? You soaked me!
Monica: I'm getting married today! I think I just cracked a rib. But I don't care, because today's my wedding day!
My day is finally here!
Phoebe: You know, she might not even notice he's gone.
