Ross's lesbian ex-wife Carol is pregnant with his child, and he doesn't like her choice of last name for the baby. Rachel finds out that her ex-fiancé went on what would have been their honeymoon with her maid of honor.

Monica finds it difficult to break up with her latest boyfriend whom everyone likes; Chandler is reunited with his beloved cigarettes; Phoebe receives a large sum of money.

While the men attend a hockey game and end up at a hospital, a delivery man accidentally brings a pizza meant for George Stephanopoulos, who lives across the street from the girls; they decide to peek at the former White House advisor with their binoculars.

While Chandler and Phoebe decide to break up with their significant others on the same night, Ross helps Rachel do laundry and considers the evening a first date. Joey has Monica pose as his new girlfriend, because he wants to get back with the girl he just dumped.

Joey gets his big film break when he's hired to be Al Pacino's stunt butt. Ross tries to be less conservative and Chandler thinks his fantasies have come true when he has an affair with a married woman.

A power outage leaves Chandler stranded in an ATM vestibule with Victoria's Secret model Jill Goodacre, whom he desperately tries to impress, Ross tries to ask Rachel out on a date, and Joey learns that Monica used to be infatuated with him.

Monica and Ross mourn the death of their grandmother with a little help from the gang, and Monica and her mom come to an unspoken understanding about the relationship between mothers and daughters. Meanwhile, Chandler is irritated by office speculation that he is gay.

Monica's first Thanksgiving dinner for the gang goes horribly wrong when they all run to the rooftop to see the runaway Underdog balloon from the parade.

The gang makes--then breaks--a pact to celebrate New Year's Eve without dates. Ross compensates for his loneliness by getting a roommate, a monkey named Marcel.
