"The PowerPuff Girls" is not a show for children. I just realised that. Well, I'm sure most children don't care, but still...
I take evidence from an episode I just saw where "The Professor" meets Ms. "Ima Goodlady". He's going on a date with her, y'see. The girls are helping him get ready. Innocent enough stuff. the then line and visual comes; the lil' blue 'girl says:
"..and one of these..."
...and slips a small, white square (with a circle on it?) into his breast pocket. Yes, we all know what it was. Children won't get it; adults just blush.
This event, however, does not detract from the fact that The PowerPuff Girls kick extreme ass.
