Following Rachel's acceptance of Joey's accidental proposal, confusion reigns as Rachel wonders whether it was the right thing to do and Phoebe can't seem to mind her own business. Finally, Rachel, Ross and Joey get together and figure out that no one was actually going to propose. Meanwhile, Mr. Geller walks in on Monica and Chandler having sex in a closet.

Chandler, having trouble getting enough sleep at home, falls asleep in a meeting and accidentally agrees to run his company's Tulsa office. Emma won't stop crying after Rachel interrupts her nap; Monica and Phoebe try to help get her back to sleep. Meanwhile, Ross is still mad at Joey, and breaks his finger trying to punch him.

After Phoebe has a talk with Ross, it prompts her to realize that she's never had a long term relationship. Monica makes a startling discovery while visiting Chandler in Tulsa. Also, Joey goes on a date with an attractive woman and discovers that her apartment seems really familiar, although he doesn't remember sleeping with her before.

The friends are looking forward to getting together and celebrating Phoebe's birthday. However, on the day of the party, Ross struggles to convince Rachel to leave Emma with Mrs. Geller babysitting, and Monica and Chandler get into an argument, after Monica discovers that he's been smoking. All of this causes them to be incredibly late, leaving Phoebe and Joey alone at a restaurant with a table for six.

Ross and Rachel hire a nanny for Emma named Sandy and things seem to be going great. However, Ross is uncomfortable having a male nanny. Meanwhile, Chandler becomes upset when Monica says that somebody from her new job is the funniest guy she's ever met. Also, after Phoebe and Mike decide to take their relationship to a new level and exchange apartment keys, Phoebe gets a surprise visit from her ex-boyfriend David.

Ross finds a way to make Emma laugh - singing Sir Mix-A-Lot's "Baby Got Back." Needless to say, Rachel isn't as amused, once she finds out. Meanwhile, Phoebe meets Mike's parents and tries her best to leave a good impression. Also, while viewing Richard's old apartment, Joey and Chandler discover a video tape with Monica's name on it, which causes Chandler to freak out, since he thinks it's a sex tape.

Rachel's sister Amy tags along for Thanksgiving at Monica's place, because her (married) boyfriend cancels their plans. While watching the parade, Joey realizes that he forgot to show up for the Days of Our Lives cast float, and he asks Phoebe's help to come up with a believable lie. The dinner goes fairly well, however, Monica constantly obsesses about anybody damaging her best china. To make matters worse, Amy comes up with a crazy scenario involving Emma, which sparks a massive argument among the gang.

Joey becomes convinced that Monica is having an affair, after Chandler sneaks back into town without him knowing, in order to have some alone time with his wife. Meanwhile, Rachel and Phoebe have a girls night out, and Rachel gives her phone number to a guy they meet at a bar. Also, Ross and Mike try to hang out together but it doesn't go very well, since they can't find a common interest to talk about.

Everyone in the gang gets a little upset when Chandler announces that he'll be spending Christmas and New Year's Eve in Tulsa because of work. To make matters worse, Monica gets quite jealous when she finds out that one of Chandler's co-workers is a former Miss Oklahoma runner-up. After doing some retrospection, Chandler decides to quit his job.

Chandler starts looking for a job and is anxious about having a baby with Monica while uncertain about his career prospects. Meanwhile, Rachel visits work and finds out that during her leave, a guy named Gavin has been temporarily assigned to take care of her job. She starts to feel insecure about her job position and decides to come back from her leave early. Also, Phoebe works as an extra on Joey's TV show and brings even more drama to the set.

Gavin gives Rachel a very interesting birthday gift while Ross begs Joey to stay away from Emma's hot new nanny. Meanwhile, Mike meets and then accidentally murders Phoebe's unusual pet.

A night at Mike's piano bar gives Monica a very showy moment in the spotlight. Ross struggles to move on after witnessing Gavin and Rachel kiss. Meanwhile, Chandler employs his secret skill to repair Joey's botched eyebrow-waxing job.

Phoebe and Joey purposely set Ross and Rachel up on bad dates in the hopes they'll get back together. Meanwhile, Monica and Chandler babysit Emma, and aren't being as responsible as they should be.

Joey endures a draining audition at the hands of a pompous actor-director. Ross and Phoebe discover a secret link after being mugged together on the street. Chandler's advertising internship gets off to an impressive start.

While reviewing their monthly expenses, Monica and Chandler discover that their situation is less than stellar. This results in Monica asking Joey to lend her some money without telling Chandler. When Chandler eventually finds out, Joey comes up with a lie that Monica needs the money for breast enhancement procedure. Meanwhile, Phoebe gets really excited as she and Mike decide to move in together, but her excitement quickly dissipates once she discovers that Mike doesn't see himself getting married ever again. Also, Rachel's attempt to baby-proof the apartment tampers with a frustrated Joey's sanity.

Chandler's jokey entry on his and Ross's college website leads to a faux burial service for the allegedly dead and obviously unpopular Gellar. Meanwhile, Joey is unwilling to give his favorite stuffed animal, Hugsy, to Emma. And Phoebe asks Monica to help her avoid a post-breakup tryst with Mike.

Monica leads the gang, except for a scoffing Ross, to purchase a bunch of lottery tickets for the multi-million-dollar powerball jackpot. However, as they gleefully plot about how they will spend the fortune if they win, they start bickering among themselves until Phoebe takes matters into her own hands. Meanwhile, Chandler frets as he waits for a phone call about a hiring job position and Rachel thinks baby Emma is close to saying her first words.

Rachel dreams about a romantic encounter with Joey after a visit to the set of "Days of Our Lives." Chandler buys a non-refundable weekend getaway for himself and Monica, but when she can't get time off at work, Ross joins him. Meanwhile, Phoebe drives people away from Monica's restaurant with her terrible guitar playing.

Joey doesn't tell the gang about his plans to throw a party on the roof of the building. He also hides the fact that he's invited the "Days of Our Lives" cast, since the girls embarrass him when they meet stars. Rachel discovers the truth about the party and soon, everybody knows (except for Chandler). Ross meets a new colleague and, instantly attracted to her, invites her to the party. Rachel and Monica go the party and act like crazed fans while Ross is intimidated by Charlie's former boyfriends. Meanwhile, Chandler is at a play alone. At the end of the party, Rachel is looking for Joey and Ross is looking for Charlie, and they find Joey and Charlie kissing.

Chandler and Monica court embarrassment when they secretly go to a fertility clinic for tests that will determine their family plans, until an old acquaintance runs into them. Ross hides his feelings for Charlie to help Joey woo her. Rachel sneaks into a spa for a massage and hopes that Phoebe won't find out and feel betrayed.

When Monica and Chandler learn of their chances for natural conception, they resort to interviewing unsuspecting male candidates to find the perfect match for one who could inseminate her. Elsewhere, Phoebe is incredibly nervous about going to a party that Mike will be at--until she bumps into David. Meanwhile, Rachel finds herself being mean to Charlie because of their common romantic interest in Joey, and Ross works hard on a lecture he hopes to present at a paleontology convention in Barbados.

Chandler gives David advice that culminates in David deciding to propose to Phoebe. However, Phoebe is still in love with Mike. Monica meddles and calls Mike, who shows up in Barbados and interrupts David's marriage proposal with one of his own. Phoebe chooses Mike, although she doesn't accept his proposal. Meanwhile, sparks fly between Ross and Charlie when they spend some time together rewriting his speech.

Charlie and Joey break up, and Rachel finally tells Joey about her crush on him. He decides nothing can happen because Ross is a good friend, but after he sees Ross and Charlie kissing, he heads back up to Rachel's room where the two kiss and shut the door. Meanwhile, Monica and Mike compete at a game of ping pong.
