Never use naughtiness in mixed company, unless your witticism is so funny that your audience will shoot tears of happiness out of their eyes with a velocity sufficient to powerwash a small bus. Any joke that falls short of that standard will make you lose respect in the eyes of everyone except your best friends, who, as you know, lost respect for you long ago.
I'm the perfect girl. You read about me in Maxim or whatever. I tell dirty jokes like I'm one of the guys, and I'm sitting there in my panties and bra so you can see I'm a piece of ass in the bargain. Except I'm real, so I come with all kinds of complications.
