With graduation approaching, Rory (Alexis Bledel) is happily looking forward to attending the Stars Hollow High School prom with Jess (Milo Ventimiglia), but he gets some surprising news from the principal (guest star Lawrence Hilton-Jacobs, "Welcome Back, Kotter"). Lane's (Keiko Agena) band makes its debut at a big party, but the evening ends on an ugly note when the long-standing animosity between Jess and Dean (Jared Padalecki) finally erupts into a fist fight. Meanwhile, Lorelai (Lauren Graham) gets roped into serving on the parents' committee for the Chilton graduation party, putting her back in contact with a very uncomfortable Max Medina (Scott Cohen).
