Chicks dig boys who misbehave and engage in mischievousness. Engaging in mischief is a high end form of flirting. The guy does something he knows he's not "supposed to"(demonstrating independence), comes up with a clever way of trying to get away with it (demonstrating intelligence), but also does so right in the face of the girl daring her to challenge him on it (demonstrating confidence). This usually results in humor, a rolling of the eyes and a further endearment of the boy to the girl.
A perfect example of this is Nathan Fillion. Not just on screen, but also off screen his character, regardless of the show, is always scheming a little. Always trying to put one past the female lead role. It also helps that he's a good looking fellow, but if it weren't for this personality (either his real life personality or the personality of the characters he plays) he would not be the star of Castle which is predominantly watched by women.
To show you what I'm talking about see below:
If you can display such cleverness and mischievousness, it can only improve your game.
Actually, becoming a study of Nathan Fillion wouldn't hurt. Watching Captain Malcom Reynolds in Firefly is a must for everybody (not just to learn how to be mischievous, but it's one of the best series out there), and if you can stomach the show, Castle is not the worst either. Though methinks most girls will just watch Castle because it's high end chick lit. Actually, now that it's November, you should just buy either for the loved ones in your life for Christmas.
