Monica and Chandler decide to host a costume party for Halloween. Monica buys Chandler a pink bunny costume and makes him wear it, which he doesn't like at all (she wanted to get him a costume to dress as The Velveteen Rabbit, his favorite childhood book, but instead of it being brown and white, the pink bunny costume was all she could find). However, when Ross comes as "Spud-nik," his clever play on words combining the Russian satellite Sputnik and a potato, he doesn't have the worst costume anymore.
Phoebe bumps into Ursula, who is getting married in a week, so she invites her in return for Ursula's invitation to the wedding. Ursula's brings her fiancé, Eric, to the party, where it turns out that Ursula has only met him two weeks ago. She has also been lying to him about virtually everything: she told him that she's a teacher, they were both in Peace Corps, build houses in Uruguay and was member of a church, which she all didn't. When Phoebe can't stand it any longer how Ursula is lying to Eric, she tells him everything about her, leading to them breaking up.
Rachel is trying to be good with children by handing out candy to trick-or-treaters, but she fails already with the first one by boring them with a story about fashion. The second one doesn't go any better: when a girl says "I love you" to Rachel, she dumps all the candy in her bowl. She then starts giving out money, which she's also runs out of pretty soon. For the next people she writes checks, but when Gunther brings candy again, the other kids also want to have money. When Rachel doesn't give money anymore, she ends up in a fight with a boy, to which she has to give 50 dollars to stop him cry, and also has to pose as his girlfriend for several houses. On her return, she confesses to Joey that she isn't entirely cut out for motherhood yet.
Phoebe and Monica, dressed as Catwoman and Supergirl, argue about who would win it in a fight: Chandler or Ross. They think Ross, but Chandler wants to prove them that they're wrong. To settle this, Ross and Chandler have an arm-wrestling match that goes on forever, as they are, according to Joey, both "equally weak". When Mona is looking and talking to Joey, it's starting to look really bad for Ross, so he asks Chandler to let him win. Chandler agrees, but Monica doesn't believe him when he tells her. He challenges her to an arm-wrestling match to prove it, but struggles to keep up with her strength while doing so.
