Prices really do vary for working girls.  So how do you know if you’re an Atlantic City streetwalker or one of the high-priced hookers for Spitzer?  There’s only one way to find out: the hustler meter. It works for both would-be gigolos and hoes. Plus it’s a safe time killer for work, so long as you don’t give yourself away by laughing out loud at the question that asks what kind of degree you have. [That’s my worth, on the left. I guess I agree.—Editor] [Nerve]
