Joey's new roommate Ross is bored out of his mind while on sabbatical, and shows absolutely no aptitude for relaxing and pranks. Joey is exasperated: even a part for an Italian Brooklyn male actor his age is nailed by a female celebrity, so Ross makes it his mission to coach him creating his own part by writing a script; alas Chandler's idea for a self-invented game gets Joey's attention far easier. Joey tells Ross and Chandler who are bickering about what Joey should do that he finished five pages in the library and asks them to test-read aloud - they soon finds it's a script for the two of them to make up.
Phoebe is determined to 'spread joy' all over the city while dressed as Santa's elf collecting for charity, but then a woman passing by mistakes the bucket people are supposed to put money into for a bin (the bucket Phoebe has decided to use does look a bit like a bin from the outside) and throws her trash into it, and a smoking man passing by makes the same mistake and accidentally sets the money on fire when he throws his cigarette into the bucket, thus reviving 'street Phoebe'. However, complaints about her attitude result in her being moved to another spot.
Tired of Rachel's hopelessly procrastinating 'plan' Monica plainly asks Danny 'who ignored her on purpose' to date Rachel, and he immediately accepts, much to her delight. However, she gets suspicous when she later sees him with his arms around a girl in the subway, but at his apartment finds that it's just his sister Krista, yet instead of relieved she is rather appalled at how physically close and childish the adult siblings still are, and the other friends concur. Though the relationship between Danny and Krista does not really appear to be incestous, as they do not really appear to be sexually attracted to each other, their relationship apparently hasn't changed in any way at all since they were children-Krista still feeds Danny cake off of her fingers, and still wipes stains off of his clothes for him, even when the stains in question are on the crotch area of his jeans (which Rachel, Monica, Joey and Chandler discover much to their shock and disbelief after witnessing her accidentally drop the cake onto his lap) and Danny still playfully chases his sister around and tickles her, even when she's half naked. It appears as though the siblings have bizarrely not developed any physical intimacy issues upon growing up at all, causing Rachel, Monica, Chandler and Joey to find their relationship disturbing. Rachel goes to Danny's apartment and tells him she wants to break up with him. He tries to persuade her to change her mind, seemingly not understanding how she could find anything wrong with his relationship with his sister, but when Krista reveals that they also still take baths together, Rachel fearfully runs out of the room.
In the final scene, Joey has written another script for Monica and Rachel; however, they find it disgusting and walk out, much to Joey's dismay, who replied that "the handsome man was just about to enter".
