My Mother's a Lesbian

I watched the funniest episode of Gilmore last night. Luke got roped into helping with the sets for the school play. He shows up to build and one of the kids he is working with says, My mother's a lesbian! Then proceeds to ask Luke, Do you know any lesbians? When the kid doesn't know what a Phillips head screwdriver is, the kid says - how am I supposed to know, My mother's a lesbian!

I can't find it online but it is Season 5, episode 15.
