One's Got Class and the Other One Dyes (S03E04)

The Stars Hollow Parent Teacher Association invites Lorelai and Luke to speak at the high school's career day, but when the students bombard Lorelai with questions about her teenage pregnancy, the PTA moms turn ugly. After discovering that her mother, Mrs. Kim (recurring guest star Emily Kuroda), wants her to go to a conservative religious college, Lane asserts her independence by dying her hair purple--with Rory's help.
