Joey is very excited when he gets a Catholic Italian immigrant part in a rising director's next film, until his agent tells him it has an essential full frontal nudity scene. Just as Monica has convinced him a movie career is worth the nudity scene, Joey finds out that he can only get the part if he is uncircumcised, which he is not. Monica comes up with ways to make it look like he is, deciding on using silly putty. When Joey has to show the director however, the silly putty falls off and he doesn't get the part.
Monica's and Ross's cousin, Cassie Geller, stays with Chandler and Monica until their wedding, but as the little girl has grown into a supermodel since they last saw her, Chandler's oogling requires her to stay at Ross's apartment instead. Ross can't help oogling her as well, and while watching a movie convinces himself that she "wants it" too. He makes a move and Cassie's negative reaction leaves him speechless.
Rachel and Phoebe realize that in two days they have to throw Monica a bridal shower. Arbitrarily calling people from her address book results in a weird crowd neither of them knows and they both forget to invite the bride. Later on, Cassie moves on in Phoebe's apartment, but Phoebe has the same reaction as Chandler and Ross, and thinks she should asks her out as she is not her cousin.
