The Day Before Mothers Day

First question: on which image of Madonna was this alter ego of Helen Morgendorffer based?

Second question: to be announced when I think of it.

• The Quiet Ones, by Smileyfax (Parts 4 and 5): Jane walked into her house and dropped her bookbag at the side of the door. As she walked upstairs to her room, she resolved to call Daria, as she wasn't in school that day. All had apparently been forgiven for Daria's fouling of the dye job and Jane's paranoia, but Jane wanted to make sure Daria was okay nonetheless. "Huh," she said aloud upon entering her room. The shades were drawn and the lights were off. She reached out to flick on the switch. "Don't turn on the lights, Jane." [Contains mature content. Hang on.]

• Unnamed story (Iron Chef: Angst Lord Time Trials), by Angelinhel (COMPLETE!): She curled up next to her best friend, for once feeling safe and comfortable.
• Unnamed story (Iron Chef: Aware of Changes), by Scissors MacGillicutty (COMPLETE!): Daria Morgendorffer awoke from uneasy dreams to the sound of her sister's voice. "DA—RI—A!" Quinn's cry came from just outside her door. "You better get washed and ready if we're going to make the Fashion Club meeting this morning!" [LATE ADD: The story is actually continued here. It is just amazing. You must read it.]
  

L8 MORNING ADDS:
I was too lazy and tired to look it up on my own, but yes, it does indeed appear to be Madonna from her 1990 music video "Vogue," another extremely specific pop-culture reference from the MTV animation staff. The relevant image is here, the video is here, and the background on the video is here. This video is apparently widely beloved by critics (said to be be one of the best music videos of all time) and was directed by David Fincher, whose movie credits are eye-popping and include The Curious Case of Benjamin Button. One heck of an alter ego reference.

Oh, almost forgot, there's a Pizza Thread at PPMB now, thanks to Brother Grimace the Great. Check it out.
