The Frances Exhibition is something that Frances Bean Cobain comes up with, be it musical or visual-arts or whatever. Sheila Sprinkle will be an influential neo-feminist figure, claiming to be the daughter of nineties underground icon Annie Sprinkle and continuing her legacy. As for the incubators, go to the "Great Expectations" storyline to refresh your memory.
And hey... who knows if some famous cartoonist and convention organizer might one day have political aspirations? :)
TRANSCRIPTION COURTESY OF JOSEPH HOUK - (BG) "Wow… What a morning. If I'd have known that
inviting Matt and Allen over would have set off all those
fireworks, I'd have told them to meet me there!" (CW)
"Don't worry about it, Beth. I could've sworn I told Allen
that I didn't want anything serious at the moment." (BG)
"It's a shame, though, right? All these years of equality,
empowerment, Lilith Fairs and Vagina Monologues… And
we're still looked down upon if we sleep around like men
do." (CW) "Well, at least we've seen the future. Once the
public hears of stuff like the Frances Exhibition, Sheila
Sprinkle and the incubator phenomenon, that will level the
playing field in a few decades." (BG) "Don't forget about
President Gran!" (CW) "Oh yeah… Wait 'til
they get a load of HER!"
