The One with the Stripper

S8, E8: Rachel nervously tells her short-tempered father, Dr. Leonard Green (recurring guest star Ron Leibman - "Norma Rae"), that she is pregnant with Ross' baby. Dr. Green then confronts Ross in his apartment, just as Ross is beginning to snuggle up with his new girlfriend, Mona (recurring guest star Bonnie Somerville - "Shake, Rattle and Roll: An American Love Story"). Meanwhile, Monica feels guilty for denying Chandler a real bachelor party, so she arranges to have a stripper perform at a belated party for him and his friends. Unfortunately, the woman that arrives is definitely not what Monica ordered. Series star David Schwimmer directed.
