So many things possible to say to make their brains lock up. One of my current favorites is "What should I drive that's going to make you happy? While you're at it- what should I wear, eat, do for a living? Please, tell me what's going to make you ****ing happy." And then just stand there and stare(raise one eye brow if you can) at them like you're actually waiting for their answer. If they give you the old "You don't have to be an *******" crap just tell them they don't either. I've got so many other VERY naughty ones, but because of legal restrictions I can't divulge them to you because you might get your ass kicked by whomever you might use them on.
