It's Rachel's birthday!!! Despite zero social interactions outside their clique, the Friends invite about 100 other "friends" to a party in a New York apartment. But oh no! Both of Rachel's parents are there! Rachel's father docks his yacht long enough to show up uninvited and the gang has to keep him away from Rachel's mother. Gunther speaks a few times. Joey sexually assaults Mrs. Green. Pretty standard stuff.  Chris continues his Friends Trivia losing streak with grace and dignity.
