7x19 "The One with Ross and Monica's Cousin"

Ross and Monica's gorgeous cousin, Cassie (Denise Richards) comes to visit, and Phoebe, Ross, and Chandler become attracted to her. Rachel and Phoebe quickly throw together a bridal shower for Monica. Joey auditions for a part which is perfect for him, apart from the fact it calls for an uncircumcised actor (which Joey is not). Upon finding out he lied about his 'downstairs' area, Monica tries to fix it so he can still get the part, using a variety of methods including Silly Putty and cold cuts.
