I don't know man, have you seen some porn outtakes? Most of those bitches are fucking CRAZY. They can turn the emotions on and off in the flick of a switch (which is actually necessary in their occupation), and quite a few of them have meltdowns off camera.

If you ever get a chance, check out the movie
