"Batgirl Is A Good Girl" is from the Batgirl page on facebook. I don't know where it came from originally, probably a fan magazine.
You see a height of 5'4" given for a number of the glamour girls, and a similar weight was frequently given for them, too. Sometimes it was a little more, which seems more reasonable. Any more they might give that weight for a girl that was quite a bit taller, which is less reasonable.
