The gang makes and breaks a pact to celebrate New Year's Eve without dates. Ross compensates for his loneliness by getting a roommate - a monkey named Marcel whom everyone adores. Well, everyone except Monica, who can't get past the faeces-throwing thing. And Phoebe faces a difficult decision when she meets a shy physicist who's thinking about giving up a fellowship in Minsk to stay with her.
Meet Marcel, the first ever monkey to star in a comedy sitcom as big as Friends!
