"The One With The Cake" is the fourth episode of the tenth season of Friends, which aired on October 23, 2003.
It is Emma's first birthday and everyone is joiningRachel in celebrating it, including Chandler and Monica, who are planning to head to Vermont shortly after the party for a romantic weekend. Rachel insists that they wait until Emma has woken up from her nap to start the party, which slightly exasperates Monica and Chandler as they want to get to Vermont fairly soon. When Rachel looks at the birthday cake, she discovers that the bakery have made a mistake and made her a cakes in the shape of a penis instead of a bunny with Emma's face on it. Rachel then storms off to the bakery in Monica's car, but forgets her license and gets pulled over for speeding. Ross heads after her with her license, asking Joey to ensure that no one leaves.
Jack and Judy leave shortly after Ross because it is getting dark and Jack cannot see very well, andPhoebe wants to leave as she has a massage client. Joey then receives a call from his agent, Estelle, telling him about an audition for which he needs a monologue prepared. After making the rest of the gang cry with a dramatic reading of one of Emma's favorite books, (a performance that he made up on the spot upon not realizing that he had to get Emma a birthday present) Joey picks up the book and tells Estelle that he has a monologue. Monica and Chandler are annoyed by his plans to leave because they had made plans before anybody else, and so they decide to make the wind-up toys that they bought Emma race to determine who has to stay.
Phoebe and Joey's toys come first and second in the race, because all that Monica and Chandler's toy does is somersault and bark. Phoebe and Joey leave, and Monica and Chandler are left alone with Emma.
By the time Ross finds Rachel on the highway, it is too late to go to the bakery. While Rachel disappointingly fantasizes about how she thought the party was going to be, (briefly stopping to yell and beep the horn at a student driver) Ross manages to turn the x-rated cake into the bunny that Rachel wanted. While they are gone, Chandler and Monica look after Emma and Chandler teaches her to hold up a finger and signify that she is one year old. Phoebe returns and declares that she slipped her client "a little something" that will wear off after five to six hours. Joey then runs in and yells at the other three to pretend to Ross and Rachel that he has been at the apartment the whole time. Ross and Rachel follow him in and tell everyone that they know that they all left, but it does not matter because they are all here now. They are filled with pride after seeing Emma's new trick and finally begin to celebrate her birthday. This scene forces Rachel to cry happily.
Throughout the episode, Ross has been filming all of the party guests recording a message for Emma to be shown to her on her eighteenth birthday. At the end of the episode, Ross and Rachel start to record their own message to their daughter, but are interrupted by a loud cheering and screaming outside. Out in the hallway, Monica, Joey, Phoebe and Chandler are racing their wind-up toys again.
The episode ends with Phoebe shrieking at her wind-up bear, "Go! Go! Go, Alan! RUN you hairy bastard!"
