I think it was this episode that had yet another one of Finch's lines about LSG's big bosom:
Maya: "Get out! Your mom's name is Fanny? As in, tushy?"
Finch: "Yeah, and you've got a huge rack. We're all God's children."
It was something to that effect, I think. That show had some good lines about her fantastic chest (usually from Finch), though.
Oddly enough, I started watching JSM for LSG, but I didn't know what she looked like; all I'd known about her was that she did the voice of Fox on Gargoyles (and what a sultry voice she did!).
