Punky and her friends were all misfits.
They just were. Punky and her wacky clothing, Allen the nerd, Margo the snob and Cherie, the only black person in the group. But they all stuck together, which is good.
"Duh. You're the idiot. Not me."
Also, isn't Margo the only one from an intact/nuclear family? Henry's raising Punky, Cherie's being raised by her grandmother, and Allen's parents divorce during the series. Many shows will have one kid who is being raised by a single parent/adopted, but the rest will be from two parent traditional households. I think it's cool this show was ahead of it's time, in a certain way.
Also, not sure if these will help, but it's worth a try:
